Fix your Benjamin or Sheridan pneumatic at home!

by B.B. Pelletier

I was flabbergasted when I saw what I’m going to write about today. An actual kit to repair a multi-pump pneumatic is a pretty rare thing. In over 40 years that I’ve been involved with them, I’ve never seen a home repair kit.

You don’t have to depend on dealers to get your spare parts
While writing about the Benjamin 392/397 bb rifles yesterday, I was shocked to see a repair kit offered for them! This represents a 180-degree turnaround in policy from the old days, when you couldn’t get these parts unless you were a dealer or a company-authorized repair station. It makes me wonder whether this is 2005 or 1905!

The new kit is good for the Benjamin 392, Benjamin 397, Sheridan Blue Streak and Sheridan Silver Streak. Who could ask for anything more?

No directions, so you have to know what you’re doing!
Pyramyd AIR put this kit together for you but there are no instructions, so you have to be handy or know what you are doing. Many of you are, undoubtedly, qualified. But, if you think you’re not, listen to your instinct. It would be better if you had an old, non-collectible airgun that you can risk ruining to test your fix-it skills. Whatever you do, don’t practice on your good Blue Streak!

This may work for you whether you’re handy or not!
If you struggle to replace the batteries in a garage door opener, this kit may not work for you. There’s still a benefit, since people who are technologically challenged often have good friends who can fix anything (they need them!). Buy the kit so your good buddy can install it for you! It’s a win-win situation regardless of your own capabilities or interests.

Buy cheap, broken-down guns & repair them yourself!
Knowing this kit is available opens up a lot of possibilities to buy guns at flea markets and pawn shops. So what if they don’t work when you get them? You can rebuild them in short order. I’ll certainly be a lot more aggressive when looking for older guns that match up with this repair kit.

These parts may not work on older guns
Remember that the Benjamin 390-series rifles have been around since 1992, and the Blue and Silver Streaks have been with us since 1949! The parts in this kit are probably not going to fit the older versions of these guns, so think about that before you take the plunge.

A second repair kit is also available!
Lest you think I’ve overlooked it, Pyramyd also sells a repair kit for the IZH 46 and 46M. The kit has seals only, but that’s all the single-stroke pneumatic needs. If you’ve used this kit, I’d appreciate hearing from you.

Are instructions next?
These two kits are going to generate a demand for instructions. While some customers will sail through the job without stopping, much of American know-how has gone south. As cars, TVs and blenders became more disposable and less repairable over the decades, two generations of Americans have grown up without doing their own simple repairs – unless they had a detailed manual (or even a video!). They expect such support and are often shocked if it isn’t instantly available, as in, “Where’s the web page?”

For both repair kits, you will need some good silicone oil, and I recommend Crosman Pellgunoil. Buy it when you order your kit so you don’t forget. Let me know how the Benjamin Sheridan repair kit works for you.

      • Orville,

        Please take your caps lock off! All caps is like shouting on the internet.

        For any information you need to contact Pyramyd AIR. This is their blog, but it is written in a different place. We have no more contact with them than you.

        Call their customer service department for parts and technical information.



          • James,

            It’s not B.B. It’s the etiquette of the internet. Did you see why B.B. said to take off the caps lock? When communicating on the internet, all caps means you’re shouting. Like a face-to-face conversation, shouting is not a good way to communicate.

            Thanks for understanding,

        • Dear Pelletier,

          First of all, thanks for the blog. This is a site I have tried to find, for years!! THANKS!

          Now, about ORVILLE and his ALL-CAPS entries. When you get our age (and I have been working on computers since 1966), you will find that your eyesite will be one of the first things to go.

          It has always been a perogitive of everyone that if someone uses ALL CAPS, then they have that right and maybe all they can see on their monitor is the CAPS. Believe me, after 42 years of computer work, I do everything off line in ALL CAPS, but I try not to hurt sensitive feelings by using ALL CAPS on the internet. After all, we are here to communicate – not declare what is right or wrong for each other.

          Just thought I’d remind you that we are not all young squirts anymore.

          • David,

            Welcome to the blog.

            Are you aware you are addressing a conversation that was started in 2005? I responded to Orville in 2014, when I should have addressed Richard. He was asking Orville a question 9 years after his comment was posted.

  2. Charles,

    There are no seal “kits” for Benjamins, as we know them. Crosman did away with the stock of parts for vintage airguns in the 1990s. What repair centers do now is make their own kits from parts they buy. It’s expensive unless you are doing a lot of fixing. It’s cheaper to send a gun to a repairman. There are four listed at this address:


    Good luck with your gun and remember to keep a pump of air in it all the time after it’s fixed.


  3. I have an older Sheridan Silver Streak with the hold down safety. I need to purchase the entire pump assembly and forearm with pins. I recieved the gun without the above parts and also need the forearm wood.
    Does anyone have any idea where I could purchase these parts or where to send the gun to to have this refitted and fixed?

  4. My wife got, from her God-Father when he died a Benjamin Franklin pump 177 cal Brass model 317 and I think the s/n is 102870, those are the only numbers on the gun. It worked fine on Starlings on my purple martin house lsat year, I kept air in it after I shot, but it won’t hold air this year. We live in Houston our zip code is 77095. I would like to repair it my self but if I can’t get a kit I will take to someone but I need a name and address and tel #. Thanks for you help! gilbert

  5. I am trying to replace a broken main spring in a Benjamin Sheridan Legacy 1000 (15,000+ shots). I have removed the broken spring, and plan to order a new one from Crosman or Pyramid. Any tips?

  6. I am looking for a repair kit for a sheridan E series .20cal Co2 Pistol. I think it is a teflon seal. The kit ideally should include tooling.
    Any ideas.

  7. I did buy the sheridan around the early 90’s. I am suprised that it is obsolete. I can probably make a seal,but the problem is getting to it. What tool do I need? I saw someone offering a kit for benjamin sheridan rifle which included tools.
    BTW I am glad I found this site, it has been of great assistance to me.

  8. Sheridan owner,

    You need a deep-hole spanner. If you want to work on your gun, I recommend you contact Dean Fletcher (google him) and buy some of his bound Crosman repair manuals. There you will see what tools are requiresd and how to make them.


  9. My father-in-law just gave my wife the Silver Streak that she used in about 1954. This gun has no markings except “Silver Streak” on the left side of the reciever and “Sheridan Products, Racine” on the other side. It has a hold down safety. How can I tell the caliber of pellet used? Will the repair kit you mention work on this gun?

  10. Hello BB
    Glad I found your blog, I am really enjoying the information. I have a question that I hope you can help me with regarding an old Sheridan pellet rifle. I am familiar with firearms but I haven’t had much to do with air rifles. The question is, how can you tell when you’re looking at an original Sheridan Sporter vs the early model of the Sheridan Blue Streak?
    I have been searching the internet and haven’t found the answer yet, I did find some info that stated there were only 1040 Sporters made and then they started making the BLue and Silver Streaks.
    I recently looked at one that has a silver colored receiver (aluminum I believe), a beautiful walnut stock, on the left side of the receiver is the word “Sheridan” and on the right side it has “Sheridan products inc Racine Wis Pat. Appl’d for”. The barrel has a blue finish on it and it has peep sights. What kind of value would there be in the old Blue Streak or in the Sporter?
    Thanks for any help you can give me.

  11. Hi BB
    My posting is also the one right above this one. Another question has surfaced as I read your web site more thoroughly. You mention in one of your postings that with the Sheridan Model A Super you have to cock it first before you pump it. I would assume from what I have been able to find out that this would also apply to the Model B sporter. As I mentioned the world of airguns is new to me so please forgive my ignorance but just what do you mean by cocking the gun first before you pump it up. What would the procedure be? At this point in time I am fairly certain that the Sheridan I am dealing with is a Sporter but I am still not positive as I am waiting to hear your reply to my earlier query.
    Thanks again in advance.

  12. Model B,

    Yes, the model B has the same valve as the model A. You do have to cock it before you can pump.

    To cock the gun, pull the bolt to the rear until you hear a click.

    Your model B is a prime collectible and should never be refinished or re-sealed by anyone except a qualified expert. Look at the oldest Silver Streak in this blog. If your gun doesn’t look like that, then it’s probably a Sporter.

    The value depends on the condition of the gun. It would range from a low of $400 for a parts gun to a high of $1,500 for one that’s new in the box. The average model B in good condition brings $800-900 these days.


  13. B.B.
    I thank you very much.You solved my problem. When I first got the gun it would not pump up and hold air, I thought it was defective. I followed your instructions and now everything is fine. The safety now works also, before it would not come out of the fire position. I will store it with a pump of air in it. Should it be stored cocked and if not how can it be uncocked without fireing it?

    I viewed the photo of the old silver streak and while the overall look is very similar it is not exactly the same as this one.

    I believe this is a sporter. It has a much larger receiver than you would find on a .22 single shot rifle,it is silver in color and I believe it is aluminum or some type of alloy. Both the barrel and the air tube fit into the front of it. It has a peep sight at the rear of the receiver, also there appears to be more barrel length past the end of the stock than there is on the streak.

    I felt it went a long ways back when I noticed it said “PAT. APPL’D FOR” on the right side of the receiver.

    I am not sure how you grade these things but I would say it is in excellent original condition and does not appear to have ever been tamperd with. The blue finish on the barrel only has a few small scuffs,the stock and its finish are pretty much 100%. It came with two round tins of Sheridan pellet’s called Bantam 5’s. There is no pellet count on the tin but they look like they would be about 250 per tin, one is full to the top and the other is about half full and judging by the condition of this gun I think they may be the original pellets bought at the same time and that may be all it was ever fired.

    After what you have told me I am not sure if it would be proper or wise to use this beautiful old gun or weather it would be better kept strictly to display for a great example of its kind that it is. It just shows quality from any and every angle.

    Do you recommend the use of Pelgun oil or any other product to protect and keep this old girl in good condition.

    Again, many many Thanks for the valuable info. and for providing such a great blog and source of help for people such as me. I find I am tuning in every day now.
    Best Regards

  14. Sheridan Sporter owner,

    Well, that is a pleasure! We saved a good old gun by your patience and research.

    From your description I believe you have a Sporter and I’d say it is probably worth between $900 and $1,200.

    Don’t shoot those old pellets. They are collector’s items, too, as is the tin. You can shoot any .20 caliber pellet in your rifle, with the Benjamin pellets being close to the originals. Pyramyd AIR has more choice than any dealer I know.

    I have several valuable old firearms and airguns and what I do is shoot them on occasion. I think your rifle would enjoy that. Oil the pump head with three drops of Crosman Pellgunoil. Buy it here at Pyramyd AIR. To see the pump head, flip the rifle on its back and open the pump handle as far as it will go. The pump head will just rise to the end of the pump slot in the bottom tube. Simply drop the oil on the head and work the pump several times to spread it around. Do this once a year and your gun will last a century or more.

    To store your rifle with a pump of air, put the air in then hold the bolt back while you pull the trigger – disengaging the sear. Bu letting the bolt go forward you then ride the hammer slowly down so it doesn’t pop the valve open.

    Thanks for your feedback and enjoy one of the finest air rifles ever made,


    • B.B-
      I have a 1975 Sheridan Blue streak that has been problem free, until the other day. I shot at a squirrel and was going to reload. I was pumping the gun and could only get 1 pump of air into it and that was it. After that the pump arm was sloppy and could hear no more “sucking of air” going into the gun after each additional pump. What possibly could have gone wrong. I’m suspecting a bad seal.

      Can you still get parts for these guns? I live in Wisconsin. Any suggestions on local service guys? I feel like I have lost my best friend. I take care of the gun very well by oiling it once a year. The gun is very accurate. I never pump it more than 7 pumps.

      Could you please give me the proper oiling techniques and also the proper techniques of storing air in them. I have never stored air in the rifle for over 40 years, but by reading the blog, I will now.

      Thanks for your help! B.B.

      • Mark R.,

        Welcome to the blog.

        You have posted a question to a report that it 11 years old. Things have changed in that time.

        Yes, the parts are still available, but I do not recommend trying to fix your gun yourself. It requires a special tool and a lot of knowledge that isn’t easy to pick up.

        Here is the man who makes all the parts for your airgun. He can repair your gun for you.


  15. I bought the C9 kit but am having trouble getting to the valve assembley. I have the gun apart but don’t see how to get it out. Does it take any special tools? Which end does it come out of? Also to get the bolt seal out does that small screw/bolt take a special socket?
    The gun is probably over 30 years old. It has the toggle safety.
    I can easily get to the pump seal. I think this is really all that is wrong with the gun but not totally sure. It will actually work but sometimes when you pump it it won’t hold a pump unless you pump it quickly to trap the air.
    As a kid I remember pumping it to twenty pumps. I had no idea that it might damage the gun. Could it?
    That pump seal is fairly hard and brittle. If this is my only problem then I am okay and can replace that easily.
    Any suggestions that may help me finish this job would be greatly appreciated.

  16. Jim,

    Let’s proceed as though the valve is okay and the pump seal is the problem. Your description of fast pumping does describe that fault.

    Yes special tool are required to remove the valve. You need to examine the valve from both ends. As old as the gun is, the valve body will be made of brass. You will see slots on the end of the valve body. A special spanner engages these slots and that end of the valve unscrews to access the inner parts.

    Make a spanner by grinding off the sides of a socket that just fits inside the pump tube. You want square ends on either side of the socket that will fit into the slots. The first time you do this you have to estimate the slot size by eyeball then check the fit. Then a long socket extension (I use one 18 inches in length) can be used with the socket to unscrew the valve end.

    If this seems daunting, don’t try it! You would do better sending the gun to a repair station than possibly damaging it in some way that makes it unrepairable.

    But as you mention, the pump head is easy to fix, so try that first. Once you fix it, remember to keep the pump head lubricated with Crosman Pellgunoil.

    Yes, over-pumping your gun could have done damage to it. The first thing to go would be the pump linkage, whose holes would have elongated from the strain. And your velocity would have been very low before over-pumping stressed the mechanism to the point that it became inefficient.

    If you need the address of a repair center, let me know. If you have an over-stressed pump linkage, there is only one place that can do the repair.


  17. Amazingly quick response! 🙂
    Thanks for the great information.
    I think I will go with replacing the pump head for now. I did buy some of the Crosman Pellgunoil you recommended too.
    It’s also amazing how much gunk is in these parts. The gun hasn’t been shot much in the past 30 or so years. One weekend at a deer camp was the most action it has had. It seems to be very accurate and powerful still to this day.
    It would be great if a good cleaning and replacing the pump head would do the trick.
    Actually though fabricating a tool to get out the valve assembly does sound like fun I won’t try it at this point. Maybe a project for another day.
    When you talk about pump linkage holes getting elongated… I may have to take another look at that to see what you are talking about. Is that easily identified? Are you talking about where the linkage arms are connected? It is a little wiggly but not bad at all.
    The gun always seemed to have plenty of power and didn’t seem to leak air that I know of. I never noticed anything like that. What would some of the symptoms of that problem be?
    Thanks again and I’ll let you know how it comes out.

  18. All I can say is:
    Replacing that pump head did the trick!
    I could tell with the first pump. This gun shoots like it’s brand new.
    I’d just like to say thank you to BB and pyramidair.
    Now to go massacre some coke cans!
    Thanks again all.

  19. Hi,

    Thanks for your blog. I’m looking for the following parts for a Benjamin Model 347 (serial T273552): trigger guard & screws, sight bridge (piece that allows you to adjust sight up and down). I live in Austin, Texas.



  20. JR,

    Your best bet is to either buy a parts gun or contact the repair stations to see if they will sell one. George Pena is closest.

    George is at heligun1@msn.com or 512-863-2951.

    You could also make what you need since it is pretty simple. All it takes is a small piece of steel and a Dremel tool.

    The part is called the elevator.


  21. Hey Guys,

    I have an old Blue Streak. I’ve been following the blog–very helpful. My son overpumpted it. I lost pressure at the valve. I made my own deep hole spanner–worked great. While wondering how to get the valve out i pumped the gun and it shot out! Now, i dont know what order they go back in. Does anyone have an exploded parts view? Or can anyone help explain me through it? I have digital camera and can take photos…

    The parts all look like the ones in the ‘repair kit’ mentioned earlier. However, i have 2 springs and only one shows in the parts kit.

    Any help would be appreciated


  22. I have a early 1970’s model Blue Streak that was working when I moved. I may have discharged it before the move. After the move it would not pump up. I have E-Mailed George Pena with no response. Can’t find a repair shop in the area which I live and I realize by reading your comments there is a repair kit with no instructions. Does anyone know of a repair shop where I can send the gun to be fixed. My last resort will be to order the kit and phone a friend to help.

  23. Reed,

    Thanks fror checkijng with George first. He may be on vacation. Here’s another place that fixed Blue Streaks:

    Rick Willnecker Contact him at airgunshop@aol.com or call 717-382-1481.

    Let me know if he cannot help you.

    Pyramyd AIR can also repair your Blue Streak. They might be the best, since they also sell the kit.

    Call 888-262-4867 and ask for Boris or email boris@pyramydair.co to confirm they can do the job.


  24. Seems several people are repairing the Blue and Silver Streaks…I am think of doing the same thing. I noticed a couple of posts up where a question was posed regarding drawings and/or pictures. I would like to learn what the fore-mentioned parts are and where they’re located on the rifle. Any update?

    Also read somewhere (may have been here) about the older model Blue/Silver Streaks may not work with the repair kits sold today. Any idea of a time frame where the kits won’t work? Mine was purchased in the mid-1970’s.

    One last question…hope it doesn’t sound dumb…what is the model number for a Blue Streak? I’ve seen “C9” somewhere.

  25. B.B.
    Thanks for the list of repairmen. George Pena is just up the road from me.

    I’ve had a Benjamin model 312, serial H153906 since I was a kid (ruined a few shirt collars pumping that baby up!).

    It no longer holds air and I was hoping to fix it myself but I saw your post that no one makes kits. I’ll bet it’s worth repairing.

  26. I have a Sheridan H series Pump pellet pistol. Anyone know anything about these? It looks pretty old. Grips are plastic and pump handle is wood. Is this normal? Any idea how to obtain a rear sight for it? I have squirrels that want to die! (They just don’t know it yet)
    In Abilene, TX

  27. Phil,

    Your Sheridan pistol is correct. If it says Sheridan on the side it was made between 1982 and 1990 in Wisconsin by Benjamin. If it doesn’t, it was either made in Racine or in NY after Crosman bought Benjamin.

    It is not powerful enough to kill squirrels reliably.


  28. Sherry,

    The best source of 5mm pellets for Wal-Mart is Crosman. Wal-Mart already does a lot of business with Crosman, and Crosman owns Benjamin Sheridan. The Sheridan Blue Streak and Silver Streak pellet rifles (Models CB9 and C9) use 5mm pellets. 5mm is also called .20 caliber.

    What you want to ask for is Benjamin Sheridan .20 caliber Cylindrical. They come 500/tin.


  29. My husbandf has an old Sheridan that won’t cock. It looks like the model is -C. Is this rifle worth repairing? He aalso has the Sheridan 500 cylindrical lead air pellets 5mm. Keep or toss?

  30. Hello there very pleased to find this site. We have 2 Sheridan “blue streaks”. One My grandmother bought for my dad in Australia in 1967 it has been totally reliable and has never been serviced or had anything replaced. The only numbers I can find on it are minute numbers to the left of the breach it says 8691A can you tell anything from this ? Our other rifle is broken. when you pump it the air seems to come straight out the barrel ? In fact you can hear it. What would be wrong with that ? I look forward to your reply . “MO” in England

  31. MO,

    Sheridan didn’t put serial numbers on their guns until the 1970s, so the number on your father’s gun is a parts number.

    I can’t tell youn much. You probably have a rocker safety Blue Streak that, in working condition is worth about $80 in the U.S. I can’t say what it is worth in the UK because there it requires an FAC. The gun develops 14 foot-pounds or more on 8 pumps, so I imagine it is difficult to sell there.


  32. I am 35 years old and have owned my sheridan blue streak for 17 years. It has had a weaver scope on it the whole time. Recently I took aim on a flying rat about 150 feet away and when i squeezed the trigger a blast of air hit my face….the barrel seperated from the pumphouse. Is this repairable??? Thanks alot.. love your blog… jim drath

  33. Jim,

    When the barrel separates it’s all over. The barrel is soldered along its entire length at manufacture. A repair job is possible, but very costly because it’s hit and miss. The Intermount they used to sell pinched between the barrel and pump tube and eventually separated the two.

    There might be repair alternatives like epoxy bonding, but I am not familiar with them.

    I think this is a job for Crosman.


  34. i am having a lot of trouble finding a reseal kit for a benjamin model 347. when i try and pump it, it just dosent build up. any idea where i can get ahold of one? thanks! -Ben, port arthur, TX

  35. I just found an old Sheridan Blue Streak 5m/m in my garage. I thought I had got rid of it years ago. It needs a pivot for the joint on the forarm to the pump. Anyone know of a place you can post old air rifles like this one for sale? eBay wont allow it.

  36. I have a Sheridan C9 vintage mid 1950’s and the gun will not hold pressure for more than 5 minutes. It looks like Pyramyd has a valve kit so I took the gun apart, removed the rear cylinder so I could get to the valve, removed the stock nut and pulled it out of the rear cylinder. How do you remove the cylinder valve to replace the O-rings, etc? I did not want to buy the kit until I saw the original to see if it matched? Thanks.

  37. A Sheridan is not an easy gun to learn on! It uses the main tube as the valve body. You have to have a special valve retaining nut wrench to remover the retaining nur.

    The tools are sold on several websites, but they don’t come with instructions.

    Here is a set of tools on Ebay:


  38. WOW! Thanks for the quick response. Since there is additional expense involved and I have never done this kind of repair, I may be better off letting a repair service fix the cylinder. Could you suggest a repair location and potential price range for repair? I live in Pittsburgh, PA. Thanks for your help.

  39. I have a Benjamin model 3120. My wife got it at a garage sell for $10. I don’t know much about it. Came with an old green BENJAMIN tin that gave no shot count but said one pound at the top. It is a .22 cal repeater. Thats all I know about the gun. Any information will be helpful.

  40. roblarry,

    The 3120 was made from 1959-1985. It is a .22 caliber rifle that’s an 85-shot repeater. It shoots .22-caliber lead balls.

    Don’t shoot the bnalls in the green tin because they have collector value. Get more .22 balls from Sunshine Airguns in Miami.

    In average condition your rifle is worth $100.


  41. B.B

    I have a 1960’s Sheridan with the rocker safety. I recently inherited this gun from my uncle. This is the same rifle my uncle taught me how to shoot on in the early 60s’.
    After having a scope mounted on it for many years, the Sheridan intermount has separated the barrel from the tube. I was able to solder the barrel back down but now it is looking kind of ratty. I would like to strip and get it nickel plated before I send it to Mac1 for the steroid treatment. I work in a musical instrument factory so I have access to buffers and there is a plating company in town.

    How do I remove the bolt? Is it necessary to remove the valve cylinder from the tube? If so, how do I remove it? I know I need to keep plating out of the barrel but do I also need to keep it out of the tube?
    Also, the butt plate is missing and I would like to know where I could find a replacement.
    Any information would be greatly appreciated.

  42. Tom,

    If you have to ask how the bolt comes out I don’t think this is a job you want to tackle. There is a plate on the left side of the receiver that comex off and the bolt retention lug is then unscrewed.

    Your gun must be 100 percent diassembled before going into the plating bath. That means the pump mechanism, hammer mechanism, trigger and valve must all be pulled out.

    There are no buttplates on a rocker safety Sheridan that I know of. If yours had one, chances are someone installed it after the fact.


  43. B.B.

    I neglected to say in my previous post that the gun is completely disassembled except for the bolt and valve casing. The guts are removed from the valve assembly.
    The bolt retention lug appears to be pinned but with no exit hole. Perhaps a 1/8″ socket is all that is needed to remove the lug?
    I still would like info on removing the valve casing. I don’t want to try something that would damage it.

  44. Tom,

    I take it that you’ve alread removed the part that requires a special spanner? If not, that’s what you need. Look down inside the gun with a strong light and you’ll see what the spanner has to look like. It can be ground fron a socket that fits inside the tube.


  45. Hi, I have a crossman benjamin Sheridan 392 pa and I cant seem to find the problem. I pump the gun(once or twice) and pull the trigger nothing, when I open the gun and push in the pin on the cylinder the air is released. if you know what is wrong email me: 232.nick@gmail.com

  46. Nick,

    The hammer is failing to open the gun’s valve. The hammer could be stuck, due to too much lubrication that got gummy, or the mainspring could be broken. Also the valve could be stuck and require too much pressure to open.

    Since you know how to dump the valve, is it safe to assume you have been inside the gun before?

    Your gun needs a complete overhaul, including the replacement of springs and seals.


  47. Dear bb, I have a 392 Benjamin Sheridan. Ive opened it up before, and it dosnt look like what is included in the kit. What I need is a teflon, cylinder shaped thingy that stops the aif from leaking out, mine is slowly leaking air because it is damaged. Any ideas?

  48. Adam,

    That thingy is called a valve. It leaks because there is a nick on the edge that seals or in the brass valve seat in the gun.

    It can be refinished by chucking it in a hand drill and holding it against a fine file.

    Or contact this man about new parts:


  49. I have a CB9 that is about 20 years old. The gun would not pump air so I got a rebuild kit and replaced the piston head. now when i pump it it moves air, but will not hold it. I can hear the air moving, but it goes out the barrel. I then replaced the stem in the valve and the lead washer. still no luck. Does the valve need to glued into the black cylinder? Or is something else wrong?? Any ideas ( and please dont say to send it to get fixed ) Thx

  50. Mike,

    Whenever you rebuild a valve you should do everything at one time. I assume you did replace the valve return spring when you replaced the valve stem? It sounds like there is some dirt in the valve that’s keeping the valve from seating against the face. Or the face itself has a small nick in it.

    You mention replacing the valve stem but not the valve itself. If you didn’t replace that the gun would still leak.

    Glue isn’t necessary.


  51. rodigjl,

    Sell it for what you think you can get. The 397 is still made, so it isn’t collectible.

    You might put it on American Airguns free classified page. This one blog page probably gets five views per week, while they get several thousand views each day.


  52. good day to all. just want to ask what is wrong with my Benjamin Franklin 317 air rifle, coz i cant feel any pressure going in the cylinder. i think there is a problem with the gasket or seal which pushes the air to trap it. thanks for your help guys.


  53. Glad I found your site. I have a couple of questions I’m hoping you can help me with. I have a Sheridan Blue Streak that I purchased (I believe) sometime in the 70’S. The serial number is 012968. This rifle has seen very little use and functions perfectly. I would grade the condition to be about 90% or better. I can’t find a model number designation other than Blue Streak. The forearm is straight and not stepped down as in recent models. The majojity of the components ie., bbl, air chamber, piston (nicle plated?), all appear to be made of brass. First can you date this rifle for me? Can you give me an approx. value in the above condition. Is there a schematic or exploded parts drawing available somewhere. Finally, I have way too many firearms (and no time) already and this pellet gun is just going to waste sitting in a closet. Is there a market for this rifle? Seems a shame its not being used or collected by someone interested in air rifles. My interest is in firearms. Would appreciate any info you can provide me. Thanks.

  54. Colobob,

    You have a SILVER Streak, not a Blue Streak. Same gun, different finish.

    Your rifle was probably made in 1976.

    You can sell it, Bob, but you’re making a big mistake if you do. Remember back in 1964 when Pontiac GTOs were selling for $3,000? Now some of them pull in a cool million.

    Silver Streaks of your vintage and condition bring anywhere from $100 to $135, which doesn’t sound like much right now, but in 15 years when your Ruger 77 is still worth $600, your Sheridan could be, as well. I sold a 1949 Supergrade Sheridan for $650 about 5 years ago. Now they’re worth $2,000.

    If you really want to sell, put up a free ad on the American Airguns web page and you will sell it in three days. Heck, I’ll give you $100 plus shipping for a rifle that holds and is in 90 percent condition.



  55. B.B.

    I just read your post on the repair kit offered for the Benjamin 392/297 rifles. Your post said that the kit would for the Blue Streak and Silver Streak.

    I have a Sheridan “C Series” (I think it is a Blue Streak) from about 1990, and the air leaks out down the barrel everytime it is pumped. When I clicked on the repair kit link that you referenced, it states that the kit does not fit the Sheridan Blue Streak (CB9) or Silver Streak (C9).

    Will this kit work for my air rifle?


  56. I have an old Sheridan Blue Streak from the 70’s. It would not pump up. I took another beat up one apart and looked at the pump assembly then I took mine apart. The seals on both pump assemblys are very hard and brittle. I reassembled mine and it seems to be working now. I want to know if there is somewhere that I can by a replacement seal or a piston assembly it seems like it would be very easy to replace this if availabe.

  57. Just got a leaky 392 for a little bit of cash and needs a little bit of work. First off O-rings what are the sizes? I need a # or some dimensions (ID, OD & wall) to replace them with. 2.Valve: unscrewed the valve body looked inside looks like moisture got in there and dried up and left behind hard water deposits (white flakey crust) trying to think of the best way to clean it out. (Help). Shot a few pellets through the Chrony before I took it apart it got around 600 fps with Benjamin 14.3 Diabolos. Then cocked the bolt again without pumping it up pulled the trigger then more air came out. (Didn’t over pump the time before) Weak hammer spring? (Just guessing not sure). Shouldn’t I be getting more than 600 fps? If so is it the valve, o-rings, weak hammer spring or D: all of the above 🙂 or is there more to it. I need more insight. So Thanks you I LOVE this STUFF!!! Can’t get enough & B.t.w Great Blog!!!.

  58. Thanks for the carburetor cleaner idea on the 392. Any idea on the sizes on the three O-rings. I know your really busy minding this blog.
    Should I go down to home depot? or any other ideas. thanks again.

  59. Removing the black on classic sheridan to expose brass. What product would work best? Obviously i would remove the stock first. Strange the book value only shows $125 as i paid almost that much 1987 for this one. Isnt todays brand new streak going for $150?

  60. I saw your reply to a question dated January 22, 2006 regarding repair parts/kits for a Benjamin Model 342. No parts available. Has anything changed in 2 years? Are they available now? I have queried Pyramid, Air Gun Warehouse, and George Pena (I saw you referenced him several times), but have had no response thus far.

  61. g-dub,

    Parts are no longer available and never will be available from Crosman again. They got rid of all vintage parts in the 1990s.

    You have to make the parts you need. That’s what repair centers do.

    If you need a gun repaired, contact this man:

    Rick Willnecker in PA. Contact him at airgunshop@aol.com or call 717-382-1481.


  62. My son was recently given a 1981 Sheridan model EB 20 caliber CO2 air air pistol. We have the original box and owners manual and the good is in excellent shape, however, it is leaking off gas. Is it worth repairing and if so, who would you recommend? Please email dbryant13@verizon.net Thanks!

  63. B.B.

    My father-in-law loaned me a Benjamin Franklin 3120 for keeping the squirrels off my wife’s bird feeders, but it doesn’t work. The pump mechanism seems to no longer function. I would like to get it fixed (both for the squirrels and eventually to give it back to my father-in-law), but am unsure of how to go about it. Also, I read in one of your posts that the 3120 was a multi-shot rifle, but I can’t see how you could load multiple shot in it.

    Any help you can provide is most appreciated.


  64. Mike,

    First, it’s a Benjamin – not a Benjamin Franklin. Those words on the side of the receiver are a play on the company name (a kind of joke).

    Second, are you cocking the gun before you pump? That’s important.

    Third, this man can fix it for you:

    Fourth, It’s a multi-shot, in that you don’t have to pump for each shot. Pump many times for several shots. I may be mistaken about the 3120 being multi-shot. It may only shoot once with each fill.

    Fifth, your gun shoots .22-caliber lead balls, so you need to get some. Try Groenewold.


  65. I’m looking for a seal kit for a pellet gun. All the gun says is Sheridan Blue Streak 139177. It is a lever pellet load and a stock handle pump. It had tons of power but I think it was pumped one to many times and now it has none..

    Can it be fixed? Where can i find a kit with tools & Instructions on how to do it for this gun that will work?


  66. mn503,

    Yes your gun can be resealed, but first let me ask you, when was the last time you oiled the pump piston head? That can cause a loss of power, too.

    Drop five drops of Crosman Pellgunoil on the pump piston head and work it around, then pump and fire the rifle several times, if it pumps at all.

    For a seal kit, this man should have them:


  67. I dont know when the last time it was oiled. I will try that. Do I need to go out and get that kind of oil or will another kind of oil do?

    Thanks allot for all the info..

  68. I bought a benjamin sheridan model 397pa. at a yard sale.It shoots fine but is missing the trigger guard. It is held on with 2 screws into the wood and is not the type with the trigger/ trigger guard and safety assembly in one unit . the safety is on top of the stock.Any hope ? Thanks

  69. Hi, I’ve got a Benjamin Model 347. Where can I find parts or someone to repair this rifle. A friend gave me 6 Benjamins and none of them are in operating condition.

  70. i have a benjamin model 312 and when you pump it up and cock the bolt, pulling the trigger does not release all the pumped up pressure.
    without pumping again, you can cock the bolt and pull the trigger again and it will release more pressure, although subdued.
    any suggestions ??


  71. I bought a blue streak back in 1969 for 35 bucks and it’s had many rounds shot. It has sat in my sister closet since last used by her oldest son and that’s been lets say 20 years, and I have it now.
    Now the problem is that it will not pump air, the stroke is fine but I believe things have dried out, putting oil/lube down the peep hole is my first choice of action but if I’m not succesful, what would you suggest?
    And many thanks

  72. TMC,

    I don’t know what you mean by a peep hole, but the oil has to be dropped on the pump head. Flip the rifle on its back and open the pump handle all the way, the pump head is at the start of the pump slot.

    Use Crosman Pellgunoil for this or if you don’t have it, use 20-weight non-detergent oil.

    Household oil is not good for the gun and WD-40 will ruin it.

    Always store your gun with a pump of air in the reservoir, and it will not dry out.


  73. This is an excellent blog, hugely instructive … but I would still give a lot for an exploded view of a Blue Streak. Also, please tell me why I can’t unscrew the little retaining lug on the cocking bolt. Has anyone tried to solder the barrel and block back onto the action. And when I look down the tube, I can’t see anything that could be unscrewed whatever tool you made; just a small brass button in a wider ring, probably the release valve? Thanks. JA

  74. JA,

    I don’t know why you can’t unscrew that lug.

    It takes a good jig to resolder the barrel. I have heard of it being done, but I don’t know anyone who does it.

    To see the valve from the rear, the hammer has to come out. To get the hammer out the bolt has to come out and the retaining lug is going to have to come off.


  75. Hmmm . I think I’ll have to remove the bolt (and everything else) if I’m going to try to solder the barrel and block back onto the action. But the trigger/safety retainer that is the end of the action has to come out first. Tight fit even after the pin is removed. But I don’t think the bolt itself is stopping me removing the pin and firing mechanism. Whatever, i’m going to make this little beauty work again. RS

  76. Greetings,
    I have a Benjamin .22 pneumatic, purchased circa 1990. It still shoots great, but the bolt is very difficult to push to the up position so that it can be pulled to the rear. No noticeable difference in the trigger, and no problems with the bolt once it is in the upward position. Any ideas? Should I try oiling the bolt?

  77. J.P.,

    Oiling the bolt probably won’t help. The trouble is in the J-bolt, which is the bolt locking lug located on the left side of the bolt. It you remove the cover on that side, you can see what is happening.

    This is a guess./ Another possibility is that a lead fragment is stuck in the bolt channel and has to be removed for the bolt to work smoothly again.


  78. Hi BB,

    I have a Benjamin 347 air rifle and I am looking to replace the seal that will hold air when pumped up. Is this called a pump cup?? Do you know of a place where I could purchase this or if there is a rebuild kit of some kind?

    Thank you for your help,


  79. BB, This retired toolmaker needs some advice. I have a 1974 Blue Streak. I removed the nut making a square spanner out of a 1/4″ drive socket as in a previous post. My question is how does the rest come out? The rifle could not hold the pumps and I felt it wanting to push back on the pump arm after the first pump, also what do I need to fix this after dissemblely?
    Thank you

  80. BB, I gave the Blue one pump and the valve popped out. I would like to replace all the seals. Do you know if the kit from Pymaryd will work on a 1974 model made in Racine, Wi S/N 094057?

  81. i was wondering if you could give me some information about a Sheridan Products BB gun. it says its a “Blue Streak” 5m/m Cal. i found it in an attic an assume it has been up there for at least 30 years. its in excelent condition with the exception of when you pump it there is no air pressure. any info would be helpful. thank you.


  82. Charly,

    Your rifle needs to be oiled and possibly resealed.

    Put 5 drops of Crosman Pellgunoil or 20-weight non-detergent motor oil on the pump piston head, then try to pump the gun. Read this report to see how and where to apply the oil:


    That is a Blue Streak shown in the photos..

    If the rifle needs to be resealed, contact this man:

    or this man:

    George Pena in TX. George is at heligun1@msn.com or 512-863-2951.

    You have a gun worth about $100-150. Get it sealed and always leave a pump of air in the gun between uses.


  83. Hi Folks, I received an old Silver Streak with the rocking safety. I shot it a few times and realized the Barrel came loose from the cylinder. I could see where someone had previously lightly soldered it on. What would be the best way to repair this? It is otherwise in great shape. Thanks, Dave

  84. I have a 1975 vintage Blue Streak. I purchased it at an auction, and had to hunt down a replacement safety,safety spring, screws and bolt locking plate and screws (?) for it. I also had to re-profile the trigger/sear to eliminate a hair trigger condition. Wood looks like heck, but it’s a shooter. Now I want to put a scope on. Being as the new Streaks are made by crosman, will the intermount for the new ones work on mine? What would be a good scope for this, as I understand you must use a long eye relief scope with the intermount?

  85. Aaron,

    The Intermount will work, though you may have to modify it a bit so it doesn’t put pressure on the barrel solder joint. Grind the edges of the legs so they don’t contact the solder.

    I like the Leapers UTG 4X40 Tactedge scope with long eye relief. It should be ideal for a Streak.


  86. Thanks B.B. That’s what I needed to know. Modification of the intermount should be no problem for an amateur hack like me, LOL. I have a bunch of rotary tools, files and the like at my disposal. Just have to remember to not get carried away and take too much off at first. File, check fit, file, check fit, file, check fit….and so on. I may even go the route mentioned in one of these posts for a rock solid mount using the rail on top of the intermount setup. Someday, I will find some good wood and completely restore this rifle. I like it that much. 20 cal packs a nice wallop when I plink coffee cans with it, turns em over if I hit high and centered on them. Viva la streak!

  87. Forgot to mention why I want to scope this puppy. Some guys I know have organized some indoor matches on Tuesday nights. First time out I was shooting a RWS mod. 48. Talk about fun. Can’t wait to take their money with my clunky ‘ole Blue Streak! 10m is a blast when the weather is bad.

  88. I just replaced the seals in a pre 1957 Benjamin 317. I made new “lead” seals out of .062″ lead/tin solder. it worked grate! be sure to join the seam together and file it smooth all the way around.

  89. Anonymous with the Benjamin Model 247 pump up pistol with a problem,

    Parts for your gun are not readily available to the public. In addition, many of the tools necessary to work on these gun’s are handmade by the repairmen themselves that specialize in repairing guns like yours. I would suggest you contact this excellent repairman:


  90. I have a Sheridan Blue Streak from the mid 90’s before Crosman bought them out. Today I noticed that the rifle was losing air from the breach of the gun when the bolt was open, or out of the barrel when the bolt is closed. I bought the gun new and it has NEVER been overpumped. Can I fix this problem or do you know of someone in Grand Rapids, MI area who can? Thanks!!

  91. Randy,

    Have you oiled the pump head? Have you been storing the rifle with one pump of air in it to keep the valve closed?

    Unfortuately airguns are not everywhere, so I don’t have a repair station close to you. The closest I can come is Illinois, which is a long drive. That’s this man:

    The best place to get your gun repaired is here:


  92. No I haven’t oiled it and didn’t know about keeping a pump of air in it. How do I go about replacing the two seals outside the pressure chamber IE where are they located?

  93. Randy,

    If your gun is leaking it needs ALKL the seals replaced. That’s a job for a repair station.

    But before you send it off (and unfortunately that’s what most of us have to do to get them fixed) you should oil the pump piston head please read this report:


    Use Crosman Pellgunoil for this. If you can’t find it in the store buy it from Pyramyd AIR.

    If oiling doesn’t help the gun send it here for an overhaul:

    When you get it back, ALWAYS keep a pump of air stored in the gun, so this doesn’t happen again.


  94. Wow I just want to say THANK YOU BB!

    I oiled the gun up today, and to be honest it started to seem kinda hopeless. I pumped it and fired it about ten times with little to no results. But I went outside and started shooting it a bit. When I put my ear down next to the breech, I couldn’t hear any leaking. I couldn’t believe it. It finally sealed about twenty shots after beginning!

    Thanks AGAIN!!

  95. Randy,

    For you this seems like a miracle. For me, this is another of hundreds of times I have seen this process work. If the leak is a slow one, as yours seemed to be, oiling has a 75 percent chance of success.

    Now–don’t forget to always store the gun with air in it, to keep the valve sealed and fresh. In your case, I would store two pumps–simply because the valve did leak. You let it get dry and it may have hardened a bit, so the extra pressure will help keep the valve sealed from now on.

    And oil the gun at least twice a year from now on!



  97. Casey,

    First, please take the caps key off your keyboard and type in lower case..

    Next, why don’t you post this question to the current blog? It’s located here.


    This place you have asked your question at is 4.5 years old and very few people will read it. But thousands read the daily blog at the address I gave you.

    And I wonder whether you installed the valve return spring and whether you lubricated all internal parts and seals with Crosman Pellgunoil before assembling? Those two things can add power to your gun. read this report:


    This simple oiling has fixed hundreds of leaking airguns and may help you, as well.


  98. hello i have a little problem with my benjamin 397 and need a little help!! i bought and installed the repair kit from pyramid air and the gun only seems to hold one pump of air no matter how many times it is pumped it shoots but is pretty weak!! was wondering what the problem is (which part i need to chance or did i put something in wrong) i followed the instructions. any help is appreciated thanks casey

  99. Hi B.B.,

    I bought a Sheridan for my son in the 70’s, C series, S.N. 53403.

    I stored it with the pump of air, apparently for too long, yesterday it shot a few times and now won’t hold air. I can’t find the manual or parts, is this gun worth what it would cost to send it off for repair if needed? Perhaps you could point me in the right direction….thanks…Les

  100. Hi anonymous,

    Pick up some Crosman Pellgun Oil and give you gun a squirt or two around the pump head and a couple of drops on the probe’s O-ring.

    If that doesn’t work give Rick Welnicker a call at 717-382-1481 or E-Mail at airgunshop@Aol.com.

    You posted your question on a blog that was written in Sept 2005. B.B. writes a daily blog where a bunch of good people get together and exchange ideas and advice. Please stop by and say hello at /blog/. Hope to see you there. (Lete us know how your gun is coming along.)

    Mr B.

  101. Before you send that rifle in to be fixed, let’s lubricate the pump head first. Please read this posting:


    And keeping that air in the gun wasn’t what made it leak. These guns need to be stored with a pump of air to close the valve.


  102. I have a sheridan products inc serial # 53403 it is a 5mm 20 cal pellets only does any one know how i can get in touch with sheridan products i want to know how old this gun is and any info i can get on it IT IS THE BEST PELLET GUN I HAVE OWNED and i have had it for 25years email tptj3@juno.com

  103. I have a Sheridan Blue Streak that I got as a child around 1969, model CB9. It has lost compression ability and I want to know if there is a repair kit for the piston head that an average joe can replace it with. The gun is too valuable to put in the corner. david

  104. David,

    While fixing a multi-pump isn’t difficult, there are no kiuts and it isn’t for the average guy.

    This place can do it for you:

    Before sending it in, read this blog and oil the pump piston head:



  105. BB…thanks so much for the timely response. I tried to put a few drops of oil there a few months but no change. If you walk with the rifle, the pump lever tries to drop down, there is no compression what so ever really. Send it off to your other recommendation? Thanks again so much….david

  106. BB-
    I have a Sheridan Blue Streak and I think that I have a blown gasket because when I pump the airgun it wont hold any air. I would say I am having the same problem as David(above). I live in San Diego is there any one on the west coast that does these types of repairs? What would you estimate this might cost me? Thanks for the help.

  107. Gary,

    I assume you are not the former Olympian who won gold in 1960 and '64?

    The Sheridan Blue Streak was made from about 1949 until today. But the company was bought by Benjamin in the 1980s, and then Crosman bought Benjamin in the early ;90s and todasy Crosman makes both Benjamin and Sheridan guns.

    It may be impossible to discover the exact date of your rifle, but we can pin it down to 1949-01963 or 1963-1985 by the safety it has.

    Read this report:


    and this one:


    Your rifle is worth $75-250, if it works. When determines the value is the age and condition.


  108. I have a Sheridan Air rifle its from the 1960's. The rifle won't keep any pressure in the cylinder. I don't believe that the company sells any repair kits or is even in existence any more! is there any way to fix the rifle?

  109. i have a benjiman sheridan pellet rifle "c" series serial #203529 all i know about the gun is it is OLD 30-40 years by what my dad says. Im trying to find a repair kit for the gun and all the ones i have found are for the Silver Streak and Blue Streak as well as the 392 and 397 im tentative about buying one of these kits without knowing the exact model of my rifle again all mine states is "C" series it is chambered for 20cal. pellets and will not hold air B.B. please help me identify this gun so i can use it again. Kasey Ford Ellensburg Wa. 509-201-6454

  110. Kasey,

    You DO NOT have a "Benjamin Sheridan." You have a Sheridan. Benjamin didn't own the company when your rifle was made. Sheridan is the only multi-pump maker of .20 caliber rifles in the U.S.

    What you need is a kit for rebuilding a Sheridan Blue or Silver Streak from the 1980s.

    Contact this man:


  111. Thank you B.B. after doing a little research lastnight i found Tim at Mac-1 have since decided to send the rifle to him for a steroid tune. And thank you for the clarification on the manufacturer.

    RWS model 46
    Crosman Powermaster
    Crosman Pumpmaster
    Sheridan "c" Series

    thanks again Kasey Ford

  112. I'm looking for a side cover plate for a relatively new model Sheridan Silver Streak. It covers the allen screw that functions as the bolt locking lug. Any help would be appreciated.

  113. Never ever clean the barrels of Sheridan guns. They are brass and don't need to be cleaned.

    Oil the pump piston head at least twice a year. More often if power fails.

    Always store the rifle with a pump of air in it – but with the rifle uncocked.

    That's it.


  114. I had a .177cal benjamin that i got from a friend when i was about 13. the gun was broken and i really didn't have the allowance money to send it to an authorized repair center. I ended up going to the hardware store about 20times looking for some correct orings and things, and 10 years later it still works like a champ.


  115. In the mid 70's I was given a Benjamin air rifle that was capable of shooting both lead BBs and .177 caliber pellets. I do not remember the model number but would love to have one again. I do remember that the bolt had a cupped face that you seated the BB into before you slid the bolt home. Can someone here point me towards the correct model number for this rifle, and where I might find a good used one? My recollections were that this rifle was awesomely accurate with lead BBs Any help would be greatly appreciated.

    Justin B

  116. Justin,

    Your description sounds like a Benjamin BB gun. They are not rifled and you know they are made for BBs because of the hollow bolt you mentioned.

    Any Benjamin long gun with a zero as the last digit of its model number will be what you are looking for.

    300, 310, 340, 360, 700, 710, 720 3600, 3620, 3100, 3130.


  117. Thanks BB, I guess I could be wrong about the bolt?! The reason I'm back tracking is because I seem to recall how awesomely accurate this thing was with lead BBs. I could not imagine a smooth bore barrel being that accurate. I am pretty sure the barrel was rifled so it maybe it didn't have the cupped bolt. If this was the case, I suspect it was a Model 347. What is the likelyhood of me finding this particular mode? Can you comment on the accuracy of the smooth bore BB Bejamins? Thanks for being so helpful.

  118. Justin,

    With MODERN lead "BBs" a smoothbore Benjamin could group inside an inch at 20 yards easily. With Benjamin brand lead BBs it wouldn't be that accurate.

    Modern .177 lead balls aren't BBs at all, but precision round lead balls that would fit the bore of a Benjamin smoothbore very well. Hence, they would be quite accurate at short range.

    You can find what you are looking for on the classified ads websites like these two:




  119. BB, Of the models you listed previously, which would have been the model that shot lead BBs? As stated, I received mine in the mid 70's and it was a new one. I remember shooting lead pellets out of it, but it was no where near as accurate as it was with lead BBs. Does that make sense?

    Thanks Again,

    Justin B

  120. Well BB,

    I located and purchased a Model 347 that while not abused, has been left in a closet for the last 20years. It doesn't hold air but I've contacted George Pena and will have him perform the reseal maintenance on it. Thanks for all of your advice/info. What do you advise for the best, most accurate pellets to shoot through this thing? How about lead balls, do they still make the lead BBs for these things? Thanks for the awesome site!

  121. Justin,

    The best pellet for a 342 should either be a Crosman Premier or a 15.8-grain JSB Exact. The rifle is a .22 of course.

    Round balls will work, but they offer no advantages in your rifle. They are not called BBs, because they are made of lead and they are .22 caliber. So look for .22 round balls. Just like .490 lead balls are not called BBs.


  122. Lance,

    I see you don't like my answer. May I invite you to post your question on the current page, so thousands of readers can see it? When you post to these old reports only a couple people including myself know that you have asked a question.

    Also, since there are over 200 comments attached to this particular blog, more than half the readers doesn't even know how to view the current comments, even if they know there is one to read, which none of them do.

    Come here to ask your question:



  123. Hello B.B.
    Thanks for this site! I have learned a lot. How can I tell which model airgun I have? I believe it was my grandfathers gun. All it has on it is Sheridan Products, Inc. and nothing else. It has the pull back to cock lever and the push down and hold safety. I can send a picture if you like. Thanks again!

  124. I have a sheridan blue streak sn O58804. I replaced worn riverts 20 years ago, but the rivets in pump arm are worn again, Also the pump seal does not move air. Is there a tune up I can do at home. Where can I look for rebuild kit and other parts. I have seen some parts on ebay, but have no idea if they are compatable with the model I have.

    I would like to pass the gun along to my son.

  125. I have a Sheridan air rifle that I know nothing about. It pumps and shoots fine, I would like to get some pellets for it but I'm confused about what to get. It says C series, 354321, 6mm/20cal., I don't think 6mm and 20cal. are the same thing.


  126. Hey so I have been looking all over the internet and this is where I have had the most luck.

    I have recently acquired an old air gun that was my grandfathers. It is a Sheridan C-Series of an unknown vintage. When my grandfather passed away the gun was given to my cousins, they however broke it and didn't use it very long. The part that is broken is the handle on the back of what I would call the bolt. From what I can tell it was somehow attached the the end of the bolt that that has been broken off. I pulled the bolt back with a pair of pliers and pumped it up. The gun seems to hold air. At first I was going to just weld or screw something onto the back of the bolt to pull it back with. But then I went and did some research on the internet and discovered that this gun is pretty nice and I wouldn't want to do that except in last resort. I no longer have the handle from the bolt. My cousins lost that somewhere. I would really like to know if it could be fixed in a better way than I was planing to. If it could be fixed what am I looking at for price. You know like if it is going to cost way more than the gun is worth it is probably better to just buy an new one. Though this one being my grandfathers does hold some sentimental value. There is some writing on the gun and is as follows: The barrel has a nickel finish I believe. Though the pump handle isn't flared like the new ones so it must be an older gun. It looks like it may once have had a scope on it as it has the mounts for one.

    Left side

    318648 5 m.m. (.20 CAL.) PELLET ONLY
    — C SERIES – MADE IN U.S.A —

    Right side

    ( I believe there is a number here of some sort but I cannot read it)

    Thanks a lot for your time.

  127. I was reading else where on your blog and thought one more interesting piece of information is that this gun has the rocker safety on it. Also after having read how you are supposed to store guns I checked and saw that this gun has been oiled. However the storing them with a pump of air in them I don't quite get. Any help there would be nice. I'm afraid I may have scared up the back of the bolt a bit before I realized what I had here. The gun that I have looks like the one that has the rocker safety on this page of your blog.


  128. Caleb,

    John Groenewold sells older parts like the bolt for your gun, when he has them


    You store the gun with a pump in it to keep both the inlet valve and the exhaust valve closed. That keeps dust out of the valves, which preserves them.

    Also read an do this:


    Do not use any other oil than Crosman Pellgunoil, which you buy at Pyramyd AIR.



  129. I have a benjamin 347 with some small seal problems and dosent seem to shoot very powerfully after shooting it for awhile. When i shoot it once it fires fine, but when i shoot it agian in one sitting,the pellet just kinda falls out of the barrel and it makes a weak pop noise. Any idea whats wrong? i am new to airguns, but i would also like to know who would buy it in this condition and what it would be worth? thanks b.b.!

  131. I have a Benjamin and Sheridan 137. It has wooden grips and no serial number. According to Crosman this indicates manufacturing before 1942. The brass has tarnish and the pump lever is loose but it still fires. I have no need for this pistol (I prefer the real ones), was looking for an idea on the value and who might want to purchase it! Thanks……..

  132. I have a 1946 benjamin super single shot air rifle nos. 317 in good condion with original box, pellets .22's and paperwork inculding catalog what's it worth still works to holds air good.

  133. Anonymous,

    Re: 1946 Benjamin Model 317

    There are several model 317 benjamin airguns. The major differances are a plunger/rod at the muzzle to charge the gun vs. a swinging tootsie roll pump handle under the barrel. In addition, there are trigger differances, finish differences and some even had walnut stocks. All of these differences affect value. The condition of your original box and paperwork are also critical to evaluation.

    I would suggest that in order to give you a value that you take some good close up photo's (macro setting on your camera) of these key elements and post your inquiry along with the photo's on this forum:



  134. I have two mid 70 blue straks that have diiferent problems. One will not hold air even after oil. The other the nut/ screw that holds on stock is broken off.

    Is there someone close to MI that I could send two to see if both can be repaired, or parts combined into one working unit.

    thanks agaim


  135. You guys and or gals seem to know alot about air guns.I have a Benjamin 312 with a two part bolt.Am looking for the handle for the bolt. Tried J. Groenewold and his part did not fit like I think you enthusiast would want it to fit on your pride and joy.I would even accept a used one if any of you out there have one.

  136. You have either lost or broken the retaining bolt that fits transversely into your rifle's bolt and holds it in the receiver. Take off the metal plate on the left side of the receiver and look for that bolt. Also look inside the rifle bolt to see whether the retaining bolt was sheared off.

    If you can find the retaining bolt, just put the rifle bolt back in the gun and screw the retaining bolt back into its hole. Then replace the retaining bolt cover and you're done.

    The retaining bolt may also have fallen down into the action in front of the hammer and you will have to disassemble the action further to get it out.


  137. I have a benjamin 347. It would not hold air so I got a rebuild kit. I have the gun completely apart and I am now working on the nut with the square head that holds the inner valve. I have put pb blaster on it and let it sit for two days. It is still very tight and I can't get it to budge. Any tips on getting it to unscrew without damaging anything would be greatly appriciated.

  138. Howdy–

    I have a Benjamin 392 and I'm not sure how many shots I have put through it (several hundred, at least, since 2005: thankfully, grackles are very smart birds, if you know what I mean). It is a stock rifle except for a peep sight I ordered from Midway.

    Anyway, I was over at a friend's where we can shoot the thing without scaring any neighbors, and we had nice targets set up at 50, 75 and 100 yards. . .which was great until the rifle began malfunctioning. We would pump it and all the air leaked right out the muzzle.

    So I ordered the post-1995 repair kit. But I see on here that you say a seal kit has to be fabricated.

    I'm confused. Will the kit I ordered do the trick?

    Also, I'm in George Pena's hometown. Can you give me any advice as to how receptive he is to inquiries out of the blue? I might like to tap his expertise (perhaps for a steroid upgrade) but I don't want to bug him.

    Thank you.

  139. Tom,

    How long has it been since you oiled the piston head? I'm betting that you haven't done that. A Benjamin pneumatic oiled and stored with one pump of air will continue to function for 40-50 years.

    In fact, I would bet that if you oiled the pump head right now, the gun would work again.


  140. I have a Sheridan model "C" that
    so far shoots fine. I read other
    postings on oiling and keeping a
    pump of air in the rifle always.
    How do you keep the pump of air in the rifle? Need a refresher–.
    Also, looking for 5mm pellets.
    No luck at the local Walmart or
    gun shops. Please advise.
    John– Sebring, Fl

  141. John,

    It's simple to put a pump of air into a model C Sheridan. Just pump the lever once and that's it. A model C doesn't have to be cocked first.

    You are on the internet, where most airguns and airgun supplies are sold. Stop buying pellets in discount stores and start buying better pellets online.

    Follow this link:



  142. BB,
    I've got an older model Sheridan that is in need of repair and I have no clue on how tho do it myself. I know that its a Blue-Streak, but other than that, I have no idea. The handle for the cock is broken off at the threads, it wont pump air and it needs to be refinished. I honeslty dont even know what model it is or where I should try to find parts. The only thing that it says on the gun is : Sheridan Products INC.
    Racine, WIS- Made in U.S.A.
    Other than:Hold down to fire, above the safety. I would appreciate any help you could give me!

  143. I have a very, very old blue streak sheridan and I was wondering how much money are they worth. mine is in prettey good condition although there is some rust on the trigger and a few scratches on the butt of the gun.

    I was also wondering that today I shot a few .177 cal bbs out of this gun and it worked fine. you mentioned that it has to be a 5 m/m or else it isn't a sheridan. I am now confused?


  144. Jordan,

    The Sheridan Blue Streak is ONLY a .20 caliber PELLET rifle. That is also 5mm. Steel BBs will ruin the brass bore.

    Just because air will blow the BBs out the barrel doesn't mean that it works correctly.

    Get the right caliber lead pellets for your rifle.

    Do you have to hold down on a safety button on the back of the receiver to fire the rifle? That would be made from 1963 and before. Is the safety two tabs on either side of the receiver? That is from 1963 through about 2000.

    In working condition and average condition a Blue Streak is worth about $75-100.


  145. Hi I have an old blue streak from the 1970's and I was wondering if this repair kit would work on it? Here is the link.

    the only part I need is the piston head part No. C 218 I have been trying to find someone who can repair it or get me the part when i found your blog. It has been a great help but I cant find anywhere where it says part No. or if they would actually fit. Any help would be great. Thanks

  146. I purchased a Benjamin 392 .22 cal pellet rifle from Bass Pro about 20 months ago. I have shot at most 600 rounds in that time, some at targets and some at nuisance squirrels, with great success. I have been very happy with the performance of the rifle overall. But just recently it has begun to lose air pressure if I have to leave it sitting for any length of time between shots. I have at times left it fully pumped and loaded for periods of times between shots since the squirrels move around a lot in the backyard. Maybe this wasn't a good idea. I don't really know because this is the first pellet rifle I have owned. Does it sound like the piston seal is leaking and needs replacing? If so, can I replace the seal by itself, or do I need a kit? I would definitely need directions. I'm a bit surprised to be having this problem so soon. I haven't overpumped or done anything that I know of to damage the seal. Thanks for any advice you can offer.

  147. Steve B,

    Have you been oiling the pump head regularly with pellgunoil on your Benjamin 392?

    If not, I'd suggest trying that first. Here's a how to and where to article. Just copy and paste this link into your browser:



  148. Hello B.B. I was wondering if you'd be able to help me with fixing my Silver Streak 5mm C9 i need to fix the seals and the pump head and all that stuff, and diagrams or tips and trick on how to take it apart and remove stuff etc, will really really help. Thanks in advance,

  149. Aaron,

    These are not the easiest airguns to work on. For example, do you have a set of roll pin pinches to drift out the necessary pins? There are also one or two special tools you need to make to work on this gun, plus you mush keep the insides hospital operating room clean.

    If you think you are up for that, go to this forum and ask your questions there:


    If you don't feel up to working on this gun, send it to a good repair station:


  150. B.B.

    Yeah i have some roll pin pinches and i'll need to make the " special " tools to get the job done, thanks for the link. I just inherited the C9 from my grandmothers will and i can't wait to try it out, it holds a charge somewhat takes anywhere between 6-18 pumps to get a good charge sometimes 6 sometimes 10 sometimes 18 etc. shot myself in the foot with just the air and that hurt foot still itches this morning, but yeah. Thank you for your help any other help or links will also be very appreciated.


  151. Aaron,

    Oil it with Crosman Pellgunoil immediately and store it with two pumps of air at all times. You may find that it just needs to be exercised to get back most of its power.

    Go here for the place to oil the gun:



  152. B.B.

    Thank you very much! i just oiled it and i'll let it sit for a little but with two pumps of air in it and get back to you on how it's working 🙂 how would you rate this c9? in your honest opinion. I let it sit for a little while and now it's really hard to get in that 8 pumps, but it works great. Just waiting on some 5mm pellets i ordered the other day to come in and i can try it out.


  153. Aaron,

    The Sheridan Blue Streak is my go-to air rifle. I love it.

    Always keep one or two pumps in the gun when you store it. It will hold them for years.

    Please come to the current blog page to talk, as your questions are of interest to the thousands of readers we have.


  154. I let my 10 year old nephew try my benjamin 397 a while ago, anyways, somehow a pellet got stock in the barrel, he kept pumping and inserting more pellets, kept pumping…i was able to remove the pellets from the barrel but now it doesn't hold air. I've been told it's a seal. any idea where is this seal? how to fix it?…thanx

  155. The seals in a Benjamin 397 are not simple to replace. I recommend that you send the rifle to an airgun repair station to get it resealed. That's what I would do.

    Here are twol good repair stations:

    George Pena in TX. George is at heligun1@msn.com or 512-863-2951.

    I am concerned that you allowed your 10 year-old nephew to shoot the gun unsupervised. A person that young shouldn't be shooting without adult supervision.

    We shooters have a responsibility to keep everyone safe, and supervision is an unwritten contract we have, both as shooters and as adults.


  156. BB,

    My boyfriend has a Sheridan C Series he got from his dad about 20 years ago. I am unable to locate a serial number. What can I look at to determine what type of a rebuild kit I should get for it. Also, where do I order rebuild kits and it there anyone around the Central Florida area that works on them? This is the only thing he has left from his dad and I would really like to get it working for him.

    Thank you in advance for your time,

  157. It looks like this post is been dead for a few years but I'll Shoot a question out there anyway… I am looking for a seal kit for a BlueStreak 5 mm serial #0791H. Does anyone have any ideas?

  159. I have a “blue streak” the information on the barrel says “Blue Streak” 5m/m cal. It also says it is a Sheridan product Racine Wis. Made in USA s/n is 192993 I would like to know what year the gun was made and if it has any value if it does how much is it worth.

    Thank you very much David

  160. I have a 1965 Sheridan Blue Streak it doesn’t hold air i wanna repair it but don’t know where to buy or get parts for the gun. I live in Winter Haven Fl anybody know of anybody in the area to fix it .

    • I’ve had mine out and they a small,short and specialized but that’s all I can tell you about’em Other than if you keep looking you’ll be able to find’em.
      Which one do you have?
      Have you tried Bryan & associates?


    • Aleadslinger,

      Welcome to the blog.

      Your rifle has a serial number that used to be searchable on the Crosman website


      I just looked and it appears they no longer provide this information. So, you need to call Crosman customer service.


  161. I have a Silver Streak my Grandfather got on a punch card at the tavern when I was 9 years old. I just turned 61.
    I need the tiny 4-40 threaded screw that goes thru the rear sight, mine was frozen, and broke on disassy. I have the nut, the screew is black oxide finished and has a knurled head, the threaded portion is about .75 long. I’ve looked around online to no avail.
    Any ideas where I might find this part?

  162. Hello to you all.
    I’m new on this forum and seek for some spares for my Sheridan Silver Streak no. 4691which belonged to my father in law (RIP).
    Does anybody know wich spare parts I need for this (air pressure is gone)? What is the series and year of build?
    Regards from The Netherlands.

  163. Hi!
    I used to live with my parents on some land. My neighbor was an old doctor, retired, who I used to talk to and listen to his stories. He knew shortly before his death he wouldn’t be around much longer and gave me an old air rifle. I mainly shoot .22 an 30-30 so I put it in my away due to no 5mm shot. My parents sold there property and I found it right where I left it. It’s a silver streak serial 5091. Just curious how old it is. Thanks

  164. Hello B.B.

    I have a question concerning one of my Sheridan c 20 cal air rifles. I have on that I have had since the late 70’s, It was resealed a few years ago by a very nice old gentleman who has since passed away. That gun works and functions as it did when I was a kid. I picked a second one up at an auction a few years ago that quit working a few months ago. I sent it to one of Crosman’s recommended repair people and got it back today. Unlike before, I now have to cock it first to pump it up. I called the guy, he said it is because it has such a strong hammer spring and the hammer is resting on the valve. To put one pump of air in for storage, I have to pull slightly back on the bolt which does work. Is this normal or should I send it to another repair center as there are two here in Ohio? I am pretty sure this gun was made in 1972 .

    Just a side note, I received my original in 1979 and put a Sheridan scope mount on it, which eventually separated the barrel. we sent the gun back to Sheridan in in 1982 for a new chamber and barrel so it now has a serial number for 1982. never put the scope mount back on and I still have the mount in the original Sheridan box. Love these older pump air guns and my repaired Crosman MKII

  165. Tcopeland,

    Welcome to the blog.

    All you have to do to put a pump of air in your gun is cock the bolt first. Then pump it, Then hold the bolt back as you pull; the trigger and ride the striker down with the bolt handle.

    I recommend that you leave it the way it is.


  166. BB,

    Is Pellgunoil silicone oil in 2017? They market a Silicone Chamber Oil that is not red in color. Are they different and if so, are they interchangable on CO2 guns?

  167. Hi B.B.
    I have an old Benjamin 317, and I was wondering if I should store it with one pump worth of air when I am not using it, like we do with Crosman 1322’s and 760/M4-177’s?
