I went around and around about the topic for today’s report. There are several new airguns I wanted to start reviewing, and several vintage guns I also want to look at. But the bottom line is that I had to go with Crosman’s 1077 CO2 rifle. Why, you might ask? Because this rifle is one you need to know about. It’s a classic for many reasons. Perhaps, the first one will surprise you.

The 1077 is a lookalike
The 1077 is a lookalike airgun. It’s a copy of Ruger’s famous 10/22 .22-caliber semiautomatic (rimfire) that’s been produced in the millions (6 million by 2012) since it was introduced in 1964. Most airgunners don’t think of the 1077 that way — they just like it for what it is: A fine, inexpensive .177-caliber repeating pellet rifle. But the fact is that the 1077 is patterned after and certainly named for the extremely popular 10/22.

1077 rifle and 10/22
The Crosman 1077 is actually styled after the Ruger 10/22 (top).

Ruger’s 10/22 is the most popular .22 rimfire
I’ll catch some flack for saying this, but the Ruger 10/22 is today’s most popular .22 rimfire. That doesn’t mean it’s the best or the most accurate or even the one with the most elegant design. There are even some major drawbacks to the 10/22 design, like it’s notoriously hard to assemble after cleaning, it has to be modified to be cleaned from the breech, the magazine release is difficult to operate and the bolt doesn’t stay open after the last shot is fired. You can even add that the bolt hold-open switch is difficult to work. But all that considered, more people are buying 10/22s today than any other model of rimfire.

The 10/22 is very inexpensive but is built in a modular way that allows the owner to add many times the cost of the rifle in accessories and modifications. It is to rimfires what the 1911 or the AR is to centerfires — a gun the user can customize almost to infinity with aftermarket parts. Like both the 1911 and AR-15, it’s even possible to construct a 10/22 entirely from parts not made by Ruger. By making it modular and allowing a huge aftermarket support base to build up, Ruger has assured its 10/22 of a solid future. And it’s the perfect rimfire for Crosman to copy.

Crosman often copied popular firearms
Crosman’s history with lookalike airguns dates back to the 1950s, when their SA-6 (Single Action 6) revolver was first offered. A Colt lookalike that came to market during the television Western craze, the SA-6 was the start of a long line of airguns that looked like famous firearms. Most of them were CO2, but a couple like the A.I.R. 17 and the M1 Carbine were pneumatics and even spring guns. But CO2 offers opportunities for repeating mechanisms that enhance realism, which is what Crosman was pursuing.

1077 debuted in 1994
The Crosman 1077 RepeatAir rifle came about in 1994. It’s a 12-shot repeating rifle that shoots 12 pellets with one loading. Company literature has always referred to the action as semiautomatic; but, in truth, what you have is a rifle with a double-action only revolver action. That’s important to know because it means the trigger not only fires the gun but also has to advance the circular clip to the next pellet and cock the striker spring. That means the trigger travel will always be long and even a bit crunchy when the gun is new. And don’t even think of modifying it! This trigger should stay as it is and just get better as it breaks in, as all of mine have. I’ll measure my trigger for you in Part 2.

Yes, this will be an old-style Part 1 report because there’s so much to tell about the 1077. I own 2 of them at present and have owned others over the years. This is an airgun I always have to have because of all that it can do and be. That will come out in the reports, but right now let’s look at the gun.

1077 basics
The 1077 is a 12-shot repeating pellet rifle. It’s small, at just less than 37 inches long, and light, at just 3.75 lbs. Because the stock is hollow plastic, the impression is that this is a kid’s air rifle. But that’s misleading! First, the trigger-pull is heavier than most youngsters can operate. Until they mature a little or the rifle breaks in a lot, it’ll be difficult for them to operate. Second, the 1077 is more accurate than its price would indicate. We’ll see just how accurate in a future test, but all who own the rifle know what a sweet shooter it can be. And third, the 1077 is more powerful than you might think. Crosman advertises the velocity at 625 f.p.s., and we’ll soon see how fast my rifle is with different pellets.

The length of pull is 13.25 inches, making the rifle small for adults and just right for older children. It comes with open sights that adjust for both elevation, via a stepped ramp, and windage, using a crude slot with locking screw for the rear sight leaf. The front sight has a green fiberoptic tube, but the rear sight is just a notch with no fiberoptics.

The barrel is a thin rifled steel tube. Like all barrels of this design, it’s possible for the barrel to become loose and cause accuracy problems. My experience, based on the 5 rifles I’ve owned and others I’ve seen is that it will stay tight if the owner leaves the barrel alone. But the moment you start fiddling with it, it becomes a problem. People fiddle with the barrel because other people on the internet advise them to –so consider this as good advice to leave the barrel alone.

Magazines & clips (they’re not the same!)
The magazine and circular clip are the topic that caused this to be a special report. The 1077 has a box-like magazine that contains a separate 12-shot circular pellet clip. The circular clip is loaded with pellets, then placed into the box magazine and locked in place. The box magazine is inserted into the 1077’s action, the same as any other rifle that has a detachable magazine.

The box magazine with the circular clip installed. The post in the slot is pushed forward to release the circular clip.

The clip is out.

This box magazine interfaces with the rifle’s action to advance the circular clip. And here’s how the 1077 action works. The trigger pulls a hook that pulls back on a stirrup located at the rear of the detachable magazine. That stirrup advances the 12-shot circular clip one pellet chamber, in a clockwise rotation, with each pull of the trigger.

That hook (arrow) pulls out the magazine stirrup when the trigger is pulled.

That hook pulls the magazine stirrup out, advancing the clip to the next pellet.

The BIG lesson (miss this & you might mess up)
Pay attention — because this is where you get in trouble if you over-think the 1077. Just as guest blogger Hiveseeker learned with the Winchester MP4: Every time the trigger is pulled, the circular clip advances. The pellet remains in the clip until the gun fires, but you’ll skip past pellets if you back off on the trigger and do not follow through and fire the gun.

CO2 powerplant
The 1077 uses a single 12-gram CO2 cartridge, which should please many. Crosman says to expect 50 shots from that cartridge and I would agree, but I’ll test it.

Both of my 1077s are converted to bulk operation and do not need to use a cartridge anymore. The gun I’m using for this test is the latest model with fiberoptic front sight, but this is one that has an adapter to use an 88-gram CO2 cartridge. Not only does it get hundreds of shots per cartridge, there’s a valve on the unit that allows me to shut off the gas. When I began the test for you, the cartridge that was on the rifle had been there for over 4 years and is still holding gas. Of course, I always use Crosman Pellgunoil, and I advise you to do the same with each new cartridge you install.

1077 rifle 88 gram
My 1077 has an adapter for an 88-gram CO2 cartridge. The round knob at the bottom shuts off the gas flow.

1077 rifle adapter out
This is what the adapter looks like.

Because I can turn off the gas, I can remove the bulk adapter and convert back to a 12-gram cartridge whenever I want to. So, I’ll be able to get a shot count for you from a standard cartridge. Alas, Crosman no longer offers the 1077 with this option, and the adapter sells used for more than a new rifle these days. It was a really cool thing that I would like to see Crosman bring back as an option.

So that’s what’s in store for you. This will be a detailed report on the Crosman 1077, including a 25-yard accuracy test that uses a bargain red dot sight that has recently been featured in this blog — the Tech Force TF90.

Ft. Worth airgun show update
Now an update on the show. We’re getting reservations every day now, and the hotel is filling up with both dealers and those just attending the show. Some people have made arrangements to fly in and see the show, then have their purchases shipped back so they don’t have to carry them on the plane!

I’ll be staying at the hotel with the dealers, and we’ll have a reception the night before from 7 to 8:30 p.m. It’s soft drinks and snacks, plus a chance to meet with the dealers/attendees and perhaps transact early show business. You can come to the reception even if you’re not staying at the hotel.

I’ll lead a caravan of dealers from the hotel to the show location around 4 p.m. on Friday. That way, there will be many people who know the route on Saturday morning, plus you get to see the grounds the evening before we set up. There’s no setup that evening.

Crosman Corporation has donated a Benjamin Trail NP2 rifle for a door prize, so we now have 2 door prize rifles and 3 raffle prize rifles. We plan to begin the drawings early in the show; so if you’re going to attend, get there early!

Crosman will also be unveiling two new rifles at this show — a tactical PCP they call the Armada and their new .357-caliber big bore — called the Bulldog. They’ve asked me for air because they’re flying in, so I’m asking those of you who live close by to bring an air tank or two if you can. I’ll have a carbon fiber tank and my new electric compressor to charge Crosman’s tank that they have to bring in empty. Maybe we can top off a tank or two while the show’s running.

They’re bringing Jennifer Lambert (VP of marketing), Chip Hunnicutt, a couple of engineers and one or two others so they can man a spot on the range with their new guns plus their table in the hall.

As this last month counts down, the show is coming together fast. Please register for your tables now or risk the chance we’ll sell out.

  1. Every time I hear about this gun it gives me the itch,then I remember the double action only part.It also begs the question; Why no .22 version? I do like the 88 gram adapter conversion and think the added weight would improve accuracy and feel as well as the valve should promote safe storage. I’m glad to hear about the show appearing to be so full and theNP2 door prize being added. All I can do is keep my fingers crossed and hope I can finally make it to one.

      Hey bro , how it going I have been around just busy trying to get the wife feeling better and going to docs and such.

      You said in the MP4 blog you had a couple things you wanted to run by me, so I am here and ready to talk.


      • Too bad the wife ain’t feeling good. Hope it passes soon.While I was sanding down my stock I found a crack in the forearm on either side of the mount screw that I glued and clamped. There’s about 1/4″gap between the stock and the threaded hole for both forearm screws that I’m considering making bushings for so the wood doesn’t have so much stress on it when tightened. Rubber or metal? I’m thinking rubber myself but I’m sure it will change the gun’s harmonics you’re the only other active Chinese underlever shooter here that I know of that may have seen this issue before and tried to address it.I can live with it being there but not any bigger or migrating to the other side. I found a vinyl cap( like the ones on rolls of copper tubing) to fit over that pin and am down to steel wooling the wood in preparation for stain and then Tru-oil.


  2. Buldawg,
    I hope the wife ain’t too bad and starts feelin’ better quick. If Mama ain’t happy..!I found a crack on both sides the left side forearm screw hole,I filled it with super glue and clamped it but I think I found out why it’s cracked.There’s about 1/4 “between the metal and wood with nothing but air there,I’m gonna fit a bushing/spacer to take up the slack on both sides so it doesn’t get worse or migrate to the other side.Metal sleeve,rubber washer or wood spacer? Thanks for the heads’up on Loctite being anaerobic, I don’t recall reading that but I found a soft vinyl copper tubing cap that I think I can fit over that pin just in case the duct seal doesn’t keep enough air away from it and a 2.5” spring guide that I might try to build a tophat with. Ever had a gun with a tophat?


    • Reb
      My B3-2 had cracks on both sides of the stock when I got it just about an inch behind where the two front screw holes are also. I went to a carpenter friends house to see what he suggested and he started by drilling a 1/16 inch hole right at the end of each crack so it could not continue any further and then mixed up a two part woos epoxy glue of some sort, I don’t remember exactly what it was but it was in a yellow min wax can and had two parts that he mixed up and filled in the cracks with it and said to let it sit overnight and then it could be sanded just like wood. Mine when I tighten the two front screws only has about 1/16 inch that the wood is squeezed together. if yours has that much space between the stock and action I would try to find a metal or hard plastic specter to keep the stock from being squeezed together more than an 1/16 of an inch or less. I don’t think rubber would be good because it would let the action move around to much and most likely affect accuracy.
      The key though is to drill a small hole at the end of the crack so it cannot continue to travel any farther in the wood and most any two part epoxy would be good to squeegee into the cracks and let it sit until it hardens. That’s what I did with mine and then painted it with truck bed liner in the spray can and it looks decent and almost like a synthetic stock.


      • Thanks for sharing that valuable information,I believe it was due to overtightening judging from the way the screw heads are rounded out and so much space in there.The gluing has already been done so there’s no turning back there, but you think something solid would be better than rubber? That would probably be easier than shaping rubber.I’ll see what I can scrounge up.Thanks! Still haven’t found my stain that I used on my 392 which turned out pretty good I just wish I hadn’t used polyurethane on it.


        • Reb
          Yes you need a solid spacer that is the same thickness of the stock that will fit in the hole of the stock and allow the screw to go thru it, even if you have to drill the hole in the stock out to fit the spacer and then some washers or another spacer bigger than the hole in the stock to take up the amount the stock is getting squeezed in when Tightening the screws so that there is no loading on the stock in the inward direction to keep it =from cracking again and not let the action move in the stock.

          Got to go to doc now will talk to you when I get back.


  3. Two new PCPs? You sly dog. You probably knew about them months ago. You are going to torment us for weeks now with these things.

    So be it. Let the speculation begin! From the name I would say the Bulldog is a bullpup style air rifle. I am glad that Crosman is not giving up on the larger calibers. Let us speculate a little further. Perhaps it is a revamped Rogue? That would work pretty nicely. It would also allow the tinkerers to put on a longer barrel/shroud/reservoir and still have it not be overly long for some.

    OK, that is enough to get the speculating going on the Bulldog. Let us speculate a bit on the Armada. I hope it is not a Marauder with a pistol grippy style stock. I hope it is a new air rifle with a stock more like a classic sniper rifle. Maybe they took a Marauder and revamped it with a longer .25 or maybe even a .30 barrel, Picatinny rails, etc.

    • RR,

      I have heard about and seen the Bulldog online. The Tactical rifle is new to me. I’m hoping they used the M4 upper they make and made it semiautomatic. I bought an AR because of that rifle and I would sure like to own an air rifle to go with it.


      • SideBar: I’m curious why in my Pyraymd Air Catalog the Crosman 760 Pumpmaster does not have the “Tom’s Pick” logo..Is it an oversight ?

          • I believe we can also say that the Crosman 760, along with a Daisy Red Ryder and Model 25 have been a major influence in introducing people to the fun of air guns. Yes, the Crosman 760 is very inexpensive and that quality alone is why it sold in such huge quanites and leveraged American’s into our sport. In the same manor as the $1.00 Kodak Brownie camera introduced photography to millions.
            Best wishes,

            • I collect air guns. Have a Crosman 760 First Variant, seeking a Second or Third Variant and yesterday Bought the new 2014 Crosman 760B which features 30% less pumping effort, higher velocity and new stock design. I wonder if we had a poll, how many started out with the Crosman 760 as their first air gun. Would be interesting how this legendary Crosman launched our interest.

              Orcutt, California

              • Pete
                I still have my wood stock and pump handle with a rifled barrel from the early 70’s. Then I got another 760 probably about 10 years ago when I was teaching my daughters to shoot.

                And now I think I will get one of the new 2014 models just to have one after what you just said about the updates they made.

                And I bet the 760’s are like the 10/22’s. I bet millions have been sold since they came out.

      • There is one picture on Crosman’s Facebook page that shows a close up of the Armada’s action. It appears to be a Marauder with Picatinny rails and a pistol grip type stock. I like the rails. I just hope it will fit in the other stock.

        • RR
          I looked at that picture you posted below of the Armada. And I’m with you on that. Looks Mrod to me.
          If its a .357 or a 9mm I believe I will end up with one of the Armada’s

          Oh but now something else comes to mind. Maybe the Armada barrel will slip into a Mrod breech. I can see one of my Mrods wearing a .357 barrel. Only if it could be that easy. I’m dream’n again. Will see pretty soon I hope though.

    • RR
      I’m going to post this reply just for you. I thought about this material being used for a gun before (especially a air gun) but didn’t know what air gun would be the best suited.

      After BB brought up the Armada tactical PCP it made me even think more about this.

      You have been talking for a while now about the big bore AirForce guns. I was thinking this could be the next version of the Escape UL.

      A carbon fiber composite frame. Not plastic or synthetic or whatever you want to call that plastic material stuff. Then have that big bore .357 or 9mm barrel in it. I think it would be a nice light weight and strong gun in more ways than one to have around. And you know AirForce has that futuristic look to it. I think that would be one heck of a big bore gun.

      But as usual knowing me I’m probably missing a key point and that would not be a good idea.

      I can dream though. Can’t I?

      • Gunfun1,that’s mt thoughts to about the Escape.From what I’ve read the Escape is even more powerful then the Condor in the 25 cal. because the valve is bigger and allows more air to pass. I know I can get 8 good shot and maybe a few more before it starts to drop and that is only on a fill pressure of 2000 psi and number 6 power setting.That’s were it is a tack driver for me,But with a fill of 3000 psi.seems to me and my tiny bit of understanding about these physics of air flow that it would push a 9mm or a larger round for at least 3 to 5 full power shots considering the barrel was at least 24” long for more pressure to build up behind the lead.If it meant a little longer barrel for say around 800 to 900 fps. I could deal with that to simply because its all about the air pushing a object this fast to put dinner on the table that fascinates me.

        • steve
          I hope they start bringing out more big bore airgun stuff from Crosman/Benjamin, AirForce and others.

          But it would be a unique air gun if AirForce offered a composite frame instead of the aluminum frame.

          I would have to get me another AirForce gun if they did that and redesigned the scope mounting location closer to the barrel. I don’t like playing that hold over and under game. That’s why I sold my Talon SS. I like my scope closer to the barrel.

          • Gunfun1,With ya on that!I hate that 3” over the center of the barrel stuff! But I love the dead on hole in holes the Airforce does.But if ya gotta shot up in a tree its almost like instinct shooting to the extreme with 3” over the barrel center.I don’t have that problem with the Mrod.I believe without measuring its 1/12′ over the center.But if one keeps the shots level there ain’t much of a problem.The Airforce is perfect for anything that can’t climb a tree.But then if your in a tree and shooting down the same holdover is again a ‘think about’ before the shot.I still love this gun and at 150 yrds.I can impress myself all day long and hit a quarter size target with a rest.I’ve said before and will say it again with the 22 Mrod its to damn easy shooting squirrel because the gun ‘don’t’ miss.Drop um all day long if the cross hairs is on the head and its no challenge.So I like to take out the Airforce and miss one now and then because my judgement on hold under was wrong.Does that make sense? By the way squirrel season starts this Saturday in KY.

      • John McCaslin said their big bore was going to be introduced as .50, but you could swap barrels out down to about .25. As far as looks, it will be different from what they have out now. The present frame has reached it’s limits. Yes, there are some guys building some real power houses, but they are reinforcing the frames and building custom valves.

        There are even some after market drop in kits for .30, .357 and .458, but I have only seen legitimate test data on the .30 kit by one of them. His kit I may end up with if I don’t just make it myself. I have done business with him before and would not hesitate to do such again.

        The other dude for some reason just will not do such. The only information he will put out is pictures of dead pigeons. OK, you can hit a pigeon at 40 yards or less with it. Is it accurate enough to hit a groundhog in the head at 50 yards? What kind of grouping do you get? What about velocity? FPE? He wants you to buy his kit, but he won’t tell you much about it.

        As far as carbon fiber, it is light, but working with it requires a lot of expensive, specialized equipment. I do not think you will actually save that much weight and you can go too light. Also, that stuff can be somewhat slick to hold and if it splinters, it can be a real bummer.

        Yeah, I’m taking it too serious. I must be in that kind of mood this morning.

        • RR
          They use carbon fiber on the R/C racing planes. They make the wings and fuselages out of them.

          They finish them with a very slick finish on the surface also. Very aerodynamic and slick and lightweight and strong.

          And I don’t think it would be anymore costly than making the aluminum frames that AirForce makes now.

          Here is a carbon fiber stock that Crosman has on a gun now.


    • You can Google the Crosman Armada, they’ve let a few pics of it out… I don’t think you’re going to like it. It looks like a rail gun from a sci-fi movie.

      I couldn’t find anything on the bulldog.


  4. I like the 1077’s. Its one of the guns my kids learned on. A nice little gun is all I can say.

    And cant wait to see the new Crosman guns. Tactical PCP and a .357 big bore. Now Crosman has my attention again.

  5. Wow, you’ve got to set the alarm pretty early to be first commentor on one of these blogs! One of the things I really like about the blog is that it covers all price ranges of guns, not just high end stuff most folks can’t afford. Here’s a good example of a decent rifle at a decent price.

  6. Master BB, are you reading my mind?
    I spent this week reading about the 1077 because my 11-year-old son is interested in it. Great report, once again. Thanks a lot!

  7. NBC update,Man-Powered weapons and ammunition book got here yesterday! And really looking forward to the 357 cal.surprise!I hope someday Airforce will do a big bore interchangeable barrel for the escapes.If so I’ll will get it if the ”Godfather” test it and all checks out good with reviews.HINT.

    • steve,
      Do you have plans to build anything yet? I love that kinda stuff! I keep checking to see if Joerg Sprave has posted the plans for his bullpup crossbow yet. If you do build anything please keep us posted.


      • Reb,Sorry I’ve tried to respond to ya and this D#@! dial up sometimes looses its connection while I’m typing and I lose everything including my temper.So I give up for now and my wife has showed me how to save what I type in case it happens again. I typed ya a good one about catapults but I ain’t gonna try it again today.Yep I want to build one and always have wanted to but gonna leave it alone for now.

        • steve,
          Don’t let it stress you out, it ain’t worth it. Glad you got the kinda space to build something that big! I wish I woulda thought about that kinda stuff when I did instead of blowing $50 in 12 guage &.22 shells every weekend.One of these days I’ll have my space back and be armed with the knowledge of how powerful and still inexpensive airguns can be instead of just thinking of them as BB & pellet guns. then I’d like to build a trebuchet, for punkin chunkin’ purposes 😉

  8. What happened with the facebook takeover thing last night? I made an account and clicked the link you provided to the pursuit channels page, but I didnt see any messages aside from the initial introductory messages introducing the guests. I must have not been on the right page. Anyhow hoped it went well last night for everyone, I tried my best to participate lol… Have a good one everybody!

    • Mithchell,

      You were on the right page. Did you LIKE the Pursuit Channel FB page? You don’t usually see everything on a page unless you LIKE it. Did you refresh the page?

      I’m a novice FB user and expected the page to auto-refresh when comments or replies were added. That didn’t happen. There was a large amount of activity, and I had to cut-and-paste the URL from one page to another to get it to refresh. It was crazy. Tom dictated, and I typed his answers. We were working at top speed, but we still couldn’t keep up. There was a LOT more engagement than anyone expected.

      I’m going to have to buy the “Facebook for Dummies” book so I can get spun up on FB before Tom does another event there.


    • Kevin,

      Thank you! I’m 66. I love getting older!

      I slept in, I opened gifts, rocked out to a musical card Tom & the cats gave me, and plan to have a fabulous day.

      In our house, we have a tradition: On your birthday, you get to do what you want, eat what you want and you’re always right 🙂

      Of course, I’ll still have to work today, but I don’t mind that.


  9. BB, The serial # of my 1077 is 994xxxxxx. Does that mean that it was made in 1994? I have the TF90 on it and it works very well as a rapid fire plinker. After the 4th cylinder, (48 shots) I seldom get more than 5 shots from the 5th cylinder, before the velocity falls off. I bought this rifle at a gun club flea market. It took 4 co2 cylinders and pellgun oil to get the seal working. My gun club uses 1077,s for it,s youth programs. They have been in use for many years( perhaps 10). They have never seen a drop of pellgun oil, yet they keep on working . They seem to be able to take a lot of use and abuse. Ed

    • Ed,

      I don’t think the serial number matches the year of manufacture because mine starts out 50.

      I have used my other 1077 for public shoots where we charged money to shoot at action targets. They really hold up, and by letting hundreds of people shoot one in a day, the trigger breaks in faster.


  10. Crosman will be releasing new pellets to go along with the Armada shaped like little Spanish galleons. Time the tumble so the main mast hits your intended victim in the eye and you’ll drop ’em in one shot. 8 > )

    I bought a 1077 for my daughter and she’s deadly accurate with it. Lightweight pellets (hobbys or lead-free) get near Crosman’s claimed velocity but mid-weight and up average in the 400fps range. She only punches paper so no big deal. Also hers only gets 3 strong mags off before velocity/POI start to drop. (36 rds)

  11. Hey BB,
    My 1077 came with a bulk adaptor. I would like to use 12 ounce CO2s though, sometimes. What do i have to do to retrofit it backwards? What parts are required?

    ALSO, Im one of those guys who read ‘how’ to adjust that heavy trigger. I now need to buy 2 new springs. Either im a klutz (possible…) or this shouldnt be attemped. Wish i had your good advice a month ago.


  12. Hi Tom
    All these replica guns are wonderful and I love the idea of owning a collection of all these classics at a fraction of the price of the real thing AND being able to shoot assault rifles, automatic pistols and even full-automatic sub-machine guns in my back yard. My only gripe with all of this is the CO2 power source. If you shoot with something like a Steel Storm, you need to change the cartridges very often and they are not free. You also have to wait between shots to allow a bit of warm up; the power is very low and the cartridges tend to leak if you leave the gun for more than a day or two. Why not use PCP technology? I am sure there will be a space somewhere in the gun for the air reservoir. If muzzle energy is limited to around 4 ft-lbs, they will be significantly more powerful than the average BB gun while allowing many shots on one fill. Air Ordnance has built a fully automatic .22 sub-machine gun (https://air-ordnance.com/smg-22-p-938.html)which operates on CO2, but can also be used with high-pressure air, so the principle seems to be feasible. Tom, can we ever expect a test of this gun? I know it is not available at Pyramid Air.
    By the way, is the Ruger 10/22 not modeled on the Winchester M1 Carbine?


          • Edith,

            Thanks. You told me before that B.B. was getting one to test but you didn’t know when. So it will be sometime shortly after 9/17. Great, I am really looking forward to that one. Happy Birthday to you. You are growing older much more gracefully than I.


      • I’ll be keeping an eye out for this report! I’ve still got that Tippman 98 C, and it works well.Could you please share any information you have or can find on how they converted the 98 to the SMG, I’m more interested in the valve modification if any rather than the belt feed mechanism,which has to be way to difficult for someone to replicate ? If I could get it to gravity feed round balls instead of belt feeding pellets that’s the way I’d go.I also have about 4 other paintball guns willing to donate parts if necessary. I know it’s a pipedream but that would be an accomplishment!


    • Vasco,
      You’d be interested in the series of 2240 modifications, if you haven’t read it already here is a link/blog/2014/07/crosman-2240-conversion-to-air-part-1/ It would appear as though some of the seals must be upgraded in order to seal without too much deformation. Other than that it’s pretty much straightforward, at least on the 2240.


  13. BB, Looking so forward for this one. I’ve often looked at this gun, but just wrote it off as a “kids toy bb gun”. If it shoots as you say, I’m having second thought and am getting the fever for one. Looking so forward to the rest of the review. Bradly

    • Bradly,

      As an owner of the 1077 I have to second everything B.B. has to say about this gun. I initially bought it just because it was semiauto but was quickly surprised by the accuracy. The trigger pull started out very heavy but quickly began to lighten up so that now, while I wouldn’t call it light, it is very usable and no hindrance to accuracy or enjoyment of shooting the gun. It is very sturdy. Make sure to get extra clips as you will go through one very quickly.


  14. BB, I just found a Crosman web site-Crosman date of manufacture-. It states that starting in July, 1975, the first 3 or 4 digits of the serial # is the month and date of manufacture. That would mean that my 994 means September 1994. What is the 3rd number in your serial #? As an example, 502 would probably be May, 2002. If the 3rd number is a 9, than you would not have been able to buy this rifle earlier than May, 2009. I wish that all firearms had a date on them when they were made. Ed

  15. I always wanted an adapter for my 1077, but those have been my unicorn. I heard about them, seen pictures of them but never was able to hunt one down and capture it.

    • John,

      You find them at the airgun shows. They will be in boxed sets that are complete. I sold my AS392T, which was a Benjamin 392 CO2 gun with this same option, that way. That rifle, by the way, was the airgun that inspired the Benjamin Discovery.

      Don’t wait for one to come up in an ad. They get snapped up too fast. You have to see them laying on the table and recognize what they are.


  16. I have a love hate relationship with the 10/22. Not a bad gun out of the box and can be quite accurate, but begs for mods. Aftermarket support is one of the main reasons to pick the 10/22 over other rimfires on the market. I’ll see how your report turns out on the Crosman 1077 and my have to pick one up if I like what I hear.

    Also, news of a tactical PCP from Crosman is something I look forward to hearing more about.


      • Matt, my problem is I want spend too much money on them. 10/22s are like women’s shoes, you have to have one for all occasions.

        The only thing I can truly say I don’t like is the bolt hold open level. I find it hard to use.

      • Go get one. They aren’t that expensive and there are a ton of them out there. I bought one last winter used for $75.00. It was made in 1972. I was just going to resell it but it turned out to be a great shooter for a stock gun. So, I put in some Wolff springs to lighten the trigger a bit and started shooting it for fun. This one likes CCI Standard Velocity with 1/4 inch groups @ 25 yards (Scoped).


  17. Edith,
    I may not be the first one but I would also like to wish you a Happy Birthday! And thanks for all you do here! My Mother also had her 66th birthday a couple weeks ago. Musta been a good year! Remember to take it easy on the cake so you’ll have enough room for the Champagne. I guess I missed the Facebook party, it seems I need post-it notes for everything anymore.


  18. B.B.

    AWESOME!, and I thought you had written about the 1077 years ago before I started my airgun hobby. Can you tell me how durable the 1077 CO2 face seal is? When my 1077 was new I was easily getting 48 shots out of every 12 g CO2. The last time I shot this rifle several months ago, I think I could only get about 40 shots from the CO2. I thought maybe I was just shooting too rapidly and over-cooling the CO2 and the action. I was also wondering if I may have damaged the CO2 face seal. What do you think?

      • B.B.

        That’s very good because I was always concerned that tightening the cap finger-tight was never quite enough to pierce the CO2. I was always afraid that the little bit extra tightening of the cap might be too much and cause damage to the seal.

        Reading your blog today made me want to blow-off work this afternoon to rush home, load my 1077, and shoot some targets, but alas, I can’t. Man I wish I could retire and spend more time with my airguns!

  19. The QB-36 stock is dark.Darker than I expected,I’ll probably start experimenting later,after it’s good and dry. You can definitely see the grain now but it’s long, wide and loose with quite a few knots. It’s got a nice birdseye right in the middle of the left forearm and some scallop type formations on the butt, the pistol grip is extra dark.


    • Reb
      You got the spacers and washer figured out yet to put the action back in that newly stained stock. Hope you find something to that will work without much modification or trouble.

      Let me know how it turns out.

      Got my hi-pac stuff today so it back to working on getting the 22 up and shooting and then machining the barrel top fit the crosman breech and get it put together, I will let you know how it turns out.


      • Buldawg, I had to take a step backward on the stock after I looked at it in the sunlight today. I could see diagonal scratches under my first coat of oil. I have figured out what I’ll be using for spacers and how I will be incorporating them into the forearm but it’ll still be a while before I’m ready to trim them up for their final fitting to make sure they have proper clearance for the lever. I’m not gonna get in a rush this time(I keep telling myself),I have other guns to shoot(but no other springers) and I have plenty of time.
        I got the letter from DARS today telling me I have an appointment for evaluation 9 /10/15, at least something’s finally happening! Gotta go look some stuff up.


        • Reb
          I agree to take your time and get it the way you want it and how it should be to keep the stock from cracking again with the right spacers.

          yep got my hi-pac kits and getting started on putting them back together, but taking my time also with them to make sure they are right.

          Lets keep each other informed on our progress.

          The wife is starting to feel better do I think she is out of the woods finally. just hopehe can stay feeling good.


          • My throat was tender for about 3 days after they ran that camera down it checking for arterial plaque.They gave me a glass of stuff that had the consistency of Certo or Sure-gel infused with Lidocaine that suppressed the gag reflex so they could work in a Barf-free environment, but I could tell it was swollen and made it hard to swallow for a while.


  20. Clear relationship of looks to the 10/22, but while Bill Ruger always said he intended the 10/22 to be a sort of practice/trainer for his .44 magnum carbine, most of the buying public saw it rather as a practice/trainer for the M1 Carbine. I know I keep a 10/22 decked out like the M1 Carbine (side-mounted Carbine sling, peep rear sight with bat-eared front sight.) But a funny thing happened…the great on-going .22LR drought of 2014. Now I may have to get a Crosman 1077 as a practice/trainer for my 10/22 practice/trainer for my M1 Carbine.
    Who’d of ever thought?

    • 103David
      I had never heard that Ruger made the 10/22 as a trainer for their 44 mag carbine, but if so that idea made them quite a fortune and I have 2 10/22 and an 44 mag carbine with the tube fed magazine and like all of them quite a bit. I got my 44 mag first back in the late 70s to use when hunting wild boar to go along with my Smith & Wesson model 29 44 mag so I would only have to carry one type of ammo.

      My only question as to the 10/22 being a trainer for the 44 mag is there is a world of difference in recoil between the 22 and 44 and as such the first time you would fire the 44 mag you would likely wind up with a heavily bruised shoulder due to the substantial recoil difference.


      • I actually had the .44 Carbine for a while and liked it a great deal. I found the recoil to be quite managable, more of a very authoritative push rather than a painful slap. I was not too long out of the military at that point where I’d trained on all sorts of (sometimes) ferociously recoiling beasts. But mostly they were so heavy. (Garand, M14, M60) that they really didn’t kick that much. Some were suprising, like the 3.5″ Bazooka which despite its reputation as “recoiless” was decidedly not. Some like the MG42 (yeah, really) fired so fast that its recoil impulse was more like a fire-hose rather than a firearm.
        The .44 Carbine still holds a place of honor in my list of “Ones I wish I still had.” You know, that’s the list we all have. This was before I learned how to load my own and even back then, it was so expensive to feed, shooting it was a near annual experience.
        But I will recommend, for your reading list, John D. MacDonald’s 1970 Travis McGee novel, “The Long Lavender Look,” in which Bill Ruger’s .44 Magnum Carbine has a short but undeniably starring role towards the end.

          • Funny you should say that. I’m an aficionado of the .38 Super and as you know, that’s not the most common of calibers, few pick-ups at the range and all that. So I count the casings I should be finding and last week, I came out three short out of a 9 round magazine. It wasn’t until I got home and emptied my jacket pockets that I found all three snuggled happily there. I know I hadn’t put them there but as I reconstructed the shooting session I realized they had bounced off the wall of the stall and into the pocket. Imagine that, brass that puts itself away. Now if I could but train all of them to do that…maybe get them to reload themselves too…
            On my honored list of firearms that I let get away, aside from the Ruger 44 Carbine are also an Ithaca pump shotgun and a lovely Browning take-down .22 both of which ejected straight down to one’s feet. Very neat and also convenient for left-handers like my Dad. (He loved the Garand I bought him even though, as he said, “The operating rod threatened to scoop my eyeball out with every shot.”). 🙂
            It never did.

            • 103David,

              What’s really bad is when you get a hot case down your shirt, as I’m sure you know. I’ve had cartridges put themselves away like you describe. It sounds nice but it really means a lot of extra time spent looking down on the ground at the range.


              • In the late ’60’s I found myself on the M60 Range at Fort Sill, teaching LMG to 20 year old ROTC students, and budding young 2lt types, most of which were nice fellows, eager and willing to learn. But as in any large organization, there always seems to be “one” in the crowd. Obnoxious, overbearing, and a know-it-all whose only exposure to an M60 was the CBS Evening News. This fellow seemed to know more about the A4 because he’d seen it so often on the TV show “Combat.” (But never in real life.)
                I’d love to take credit for the denouement but ’twas one of the other instructors.
                After a number of snarky comments to the lowly Specialist types, he asked why no A4 and could we find one for him to try out. “We haven’t used those in more than a decade,…sir.” A hot day there in Oklahoma that summer and tempers were a bit short, especially concerning clueless, suffering from unearned entitlement issue-summer-camp-officer-cadets.
                “If you come a little closer and view down the barrel, I can give you a few tips,…Sir,” sez the Specialist.
                The range-master E8 watches and knows what’s coming…but remains silent.
                A full-second M60 burst sends 10 rounds down range while perfectly pouring 10 red-hot casings down the obnoxious officer cadet’s shirt-front.
                As you might imagine, considerable old-time movie type action ensued, not to mention much hilarity.

        • 103David
          I was never in the military so there are a lot of weapons that I wish I had the opportunity to shoot but never got the chance to and it sounds like you got to experience a wide variety of nice weapons. I know I will never sell either my 44 carbine or my dirty harry model 29 unless there is nothing left for me to sell to survive because to me guns are survival. I will look into your suggested reading although I can tell you I have never been much of a reader because my eyes start to go to double vision after about 30 minutes of reading, now if it was available in one of those new formats where you can listen to it that would be a different story. I got the carbine so many years ago when I was big into hog hunting for monster boars in the swamps of the west coast of Florida area where the boars would get as big as cows and were won of the few game animals that would hunt you down if you did not make a one shot kill and at that time there were only a few guns that could be carried easily all day long and used in heavy brush hunting. The 44 carbine was one of those guns that had excellent close range knock down power and as I stated in my previous post allowed me to carry one ammo for both my rifle and pistol.


          • Yikes!
            Reminds of being invited to a Feral Pig hunt some years ago in Northern California when the ferals had gotten out of hand. Thinking about taking along something like, oh, gee, maybe a 9mm carbine or like that, I innocently asked, Okay, how big do they get?” Now I don’t exactly recall the number, but it was right up similar to your description, and two separate thoughts immediately collided in my mind.
            A:) First Rule of Hunting, “Bring Enough Gun! Even the M1A with fixed bayonet may not be enough for one or more of those…And I seem to have mislaid my grenade-launcher somewhere…
            B:) Second thought, “This sounds somewhat out of my league! Maybe I’ll start with bunnies and I’ll work my way up…”
            Needless to say, no pigs for me that day…
            On John D MAcDonald, he was an extremely prolific writer, authoring…many stories… And at least 20 in the Travis McGee series. Travis is a private detective, living in Florida, living on a houseboat and taking his retirement serially and early. In other words, collects his fee and then doesn’t work again until he needs to and thinks of himself as a “Knight Errant.” While the books can be tough and violent, I wouldn’t call them “hard-boiled.” The first book was published in 1964, the last in 1985 which I mention only because the society (and we) have changed some in the last half-century or so. Some folks may find them dated.
            Most people, of a “certain age” ( like you and me, and probably most of the folks reading and writing this blog) won’t care much about that.
            We lost John in 1986′ as I recall.
            In any case, if you’re not familiar with John D MacDonald, or used to be years ago, I highly recommend him as an addition to your reading list. (Note it’s not Ross McDonald, also good but a different guy, and John spelled his name MACDonald, useful to know while searching a used book-store, on-line, or assisted by a spelling impaired clerk.
            Other recommended authors would include C. S. Forester (Horatio Hornblower,) Dash Hammet (Sam Spade,) and Raymond Chandler (Phillip Marlow.)
            A Kindle might help your reading as the type face can easily be enlarged. Get the paper-white one as it presents a much brighter image. For what it’s worth, my Kindle died a couple of years ago (actually was murdered,) but there’s an app that allows almost any other device to use Amazon books. I can read anything on IPad, cell-phone, or laptop and the app is free. Amazon will sell a/this Kindle book for $10.
            The real secret, however, is garage-sales, Tag-Sales, the local Goodwill, Salvation-Army, or your local Public-library. Like as in 50 cents/ a Buck/ lots less than $10. Eternal vigilance is the price of really good reads.

          • As an addendum, be aware not all the Kindles support audio playback, so if you go that way, be sure on that point.
            Also all the garage-sale etc places I mentioned often will have collections of books-on-tape (as in cassettes.) One more thing to keep an eye out for. It’s some surrealistic to drive across Death Valley or Arches Park while listening to “Interview with the Vampire,” or “The Cruel Sea.”

            • 103David
              Yes the hogs I used to hunt were very huge and not at all scared of human. I was in my early 20s and my friend that I lived with had a hog claim to 450 acres of Champion timber company land near Cross City Florida in what is known as the green swamp area of FL. By having a hog claim, which they sold to many people for the same parcel of timber land it allowed us to hunt them year round and actually gave him ownership of all hogs on the land that his claim covered. So if you had caught a hog on part of his 450 acres of land and did not have a claim to that land he could legally take that hog from you because he owned it. We would hunt them with a couple pit bulls and large caliber guns,( even my 44 mags were not big enough to kill the 800 pounders as the bullets would bounce off their skulls and if you hit them in the side it would just piss them off ) we ran into an older man ( I say that because we were in our early 20s ) he was 45 and lived in the swamp and had hunted the hogs there all his life, he would hunt them with 8 to 10 pit bulls and 2 Airedales because the pits do, not bark when they are on the trail of a hog so the Airedales would howl when giving chase and all he carried was a 10 inch bowie knife ( no gun ). We asked him why he did not carry a gun and he said all most guns will do to the big hogs he hunted was piss them off and then you become the hunted. he told us stories of when he first started hunting them he would shoot them and end up being chased up a tree by them and have to spend the night in the tree with a 800 pound hog trying to uproot the tree all night long and he was talking about 2 foot diameter oak trees. he had had more dogs killed by hogs than he could remember because these big hogs would have tusks that were 8 to 10 inches long and razor sharp. He finally found that a hog would suffocate on its own blood in 5 minutes if you just stuck that 10 inch bowie in its throat and stirred it around like a pot of soup, of course you had to get close enough to cut its throat. hats why he would use 8 to 10 pits to catch and hold the hog down so he could kneel across the hogs jaw and shoulders while he stuck the knife in its throat. He was way braver than I was that’s for sure, he had one female pit that had saved his life more times then he could remember and this pit had over 225 holes in it that had been stitched up over the years. I do remember shooting about a 800 pounder with a 30-30 at 40 yards three time in the front shoulder back to the rear leg and it just ran off and we found three chunks of bloody meat where I had hit it, but it never slowed down and ran thru a briar patch like is was a cotton pillow.

              We never did get one of the big hogs like the man we met that lived there hunted but we caught many 3 to 400 pounders and wild boar is some good eating pork.

              And about one of those Browning take down 22 that Norinco copied several years back, I have one of the first ones made that my mom bought my dad for Christmas back in 1957 for a whopping 150 bucks, it is a very sweet and lightweight 22 that is deadly for squirrel hunting.

              I will check into the kindles for reading as that my help with my eyes being able to last longer if the print is bugger or even better if it reads to you.


              • Buldawg,
                One other thing, I work for an Ophthalmology/Surgery practice…No, I’m not an eye Doctor, but I am in charge of scanning ALL the examination charts, medical and surgical records. I get to read them all (so I know where to file them) and I can assure you they make a very interesting record of both what can go wrong, as well as what can be done to fix damaged eyes. We find, commonly, compromised eyesight is something that creeps up so gradually that many patients don’t really notice it or accommodate imperfectly the diminished view…and they shouldn’t tolerate this.
                There ‘s two things to know; One, as we age, this is inevitable. It happens to everybody. Nobody is exempt. Two, there have been enormous advances in the last few years, particularly with aging eyes (like yours and mine) that can bring eyesight back by an almost magical degree. Cataract surgery, as an example usually sends you home the same day. (Have somebody pick you up as they don’t recommend you driving yourself home.)
                How ’bout you get yourself in to one of your local Docs and see what the possibilities are?
                In the meantime, Hey, kids,wear those pesky, bothersome safety goggles anytime you even go near a BB gun, a welding rig, or throws metal/wood splinters around.
                My personal examples? As an example, on my desk,I keep one 12 gauge shotgun shell clearly stamped “DUMMY.” It’s been fired. I fired it thinking/believing it safe. It wasn’t. No powder, but live primer and shot in place. Them primers is powerful enough to spray the living room pretty good. Think about it.
                Beside that on the desk is a 9mm cartridge case with approximately 1/3 of the base blown out of it. Think about what that would have meant while not wearing safety goggles. Stings your face pretty good. Ouch!
                And my personal favorite about how this stuff sneaks gradually up on you, my Ophthalmologist, looking at my contact lenses and saying, “how can you even see through these things, they haven’t made these for at least 20 years!”
                My only excuse for the 20 year lag? “Well,”sez I, “it makes myself look better in the mirror.”

                • 103David
                  Been there and done that, I had cataract surgery in both eyes in 08 and had to go back after about 2 to 3 months and have the cobwebs laser-ed off the lens implants. now I have floaters on the retina of my right eye that I only see in my peripheral vision on the far outer right and have to be looking at a white or nearly white background to see them. I have been to an ophthalmology surgeon and had the floaters checked, he said that they are not in need of immediate attention as they are in my peripheral vision and not in my direct line of sight out of the right eye. They have been there for about 2 years and did not have insurance to have it checked till this year, but they have seemed to improved some on their own or I am just used to them.

                  The only real time that I notice them is when I am shooting my air guns and firearms that have diopter peep style sights at a target with a large white background such as when I go to our local CMP range to practice and sight in my lower powered air guns. the targets are 10 meters and have a white wall as a background behind the targets, while sighting in on the black bulls eye I see what appears to be bugs crawling down either side of the target, when I take a quick glimpse at the target outside the sights there are no bugs only when looking thru the sights.

                  I have always had issues with reading for long periods with my eyes even as a kid and wearing glasses to correct 20/200 in left eye and 20/225 in right with a lot of astigmatism, so even after cataract surgery it has not changed and I have just learned to read for 30 minutes or so and rest for 10 to 15 minutes in between reading sessions.

                  I do wear safety glasses when required as my occupation as a auto tech I have had rusty metal stuck in my eyes three or four time in the course of 45 years working on cars even with safety glasses on. Getting metal removed from your eyes is no fun and cause loss of use of the affected eye for several days.


                  • I got a job working at a muffler shop in Tyler where I was given a pair of tinted safety glasses that I was supposed to put on before going under any car. My second day ended with me going home after a glowing spark left a half inch long white scar on my cornea after bouncing from my brow to the lense and back into my eye. & Sometimes you’re the nail!


                    • Reb
                      You got that right, sometimes even using the appropriate safety equipment it still gets you. I have been stung in my eyelid while riding my motorcycle with sunglasses on where the wasp hit my forehead and bounced down into my eye behind my sunglasses and before I could get the glasses off he had already nailed me in the eyelid , luckily his stinger did not go through my eyelid and into my eye. I looked like I had been in a fight and been hit in the same eye 10 or 15 times and could not see out of that eye for a week.

                      Sometimes you just can’t win for losing.

                      Have you got your 36 back together yet or are you still working on the stock finish ?


          • Buldawg, do keep that fine Ruger .44mag carbine clean. Dirty ones can fire out of battery. Dirt + Lawyer might have something to do with them no longer being made.

    Please remind everyone that the Airsource 88 gram Bulk Adapter is OBSOLETE according to Crosman, so o-rings and parts are no longer supported.

    I have been looking for o-rings for several weeks now for the adapter shut-off valve. This is very difficult when one has to guess at the material and size (which appears to be non-standard). Crosman won’t provide part detail info. I have blown out a few o-rings testing and each trial costs me 1) an 88 gram tank, 2) cost of wrong o-rings and 3) 7-15 days waiting for the next o-ring to test.

    My 1077 came with the Airsource Bulk Adapter and is just 3 years old. This is too new to lose parts support.

      • Thanks for the link. I have been calling Bryan and Associate’s phone without any luck getting through. Due to the tone received, I had assumed the line was disconnected, rather than busy. Thanks for a link to his mail address. AB Airguns was another possible source suggested by Crosman, who has apparently been shut down for remodeling. I have left my information on their answering service, but haven’t made human contact.

        I never realized what a hassle finding the right o-rings would be. Many replacements for specific guns are listed on ebay (U.S. and U.K.), but no one lists the sizes or materials of what they are selling. I have bought kits o-ring kits (like 200-300 o-rings per kit), searched hobby shops, home repair stores, and could only find a few possible size matches that blew-out immediately when the 88 g tank was installed.

        I think I have nearly spent as much as the gun cost and dozens of hours searching. It is very disappointing.

  22. I was crawling the web today and I noticed there is a kit out now that makes your 1077 into a bulk fill co2 gun. The unit simply inserts into the gun where the co2 cartridge goes and you bulk fill it from a co2 tank much like you fill a disco with co2. I was intrigued by this and wanted this unit to use high pressure air too but the company that makes these had tried it and it can’t be done. The hammer doesn’t hit the air valve hard enough yo open it in high pressure air and cannot be modified to do so. But bulk fill with this kit gives you many more shots than a 12 gram powerlet and saves money on the hard to get 88 gram tanks. I found my 88 gram guns are fairly useless since I do not have a local source for them. So this bulk fill option seems like a good one.

  23. It’s a very nice evening here in Northern Michigan. The day was in the 80’s but it’s cooling off and the wind dropped to “0”. So, it was a great time to try out the RWS .177 Superpoints that I received from Pyramyd AIR last week. At 10 yards they were cutting one ragged hole out of the FWB 124. At 30 yards they would pick the heads off of the Cattails growing in the backyard. These look like winners.

    I will say this is a tuff one. And I may be wrong. But I think those little packs that they put inside the hi-pac up by the fill port should stay inside. I believe anyway. I have one thing in mind from what they taught us at work with air and hydraulic pressure. Its always a equal force that is inside the pressurised container. And when you pressurise a system even though the air comes in and pressurises to 3000 psi. It will not blow something around inside the container. That dry pack will just compress and stay there. It will not get blown around inside. It should not even get tore up. Mine is inside and no problems yet. So I will leave mine inside just to test and see if anything happens.

    But I will email them just to see what that say about it also. But even if they say its suppose to come out. I will leave mine in to see what happens over time. How about that for a test. 🙂

    And are you going to change to the black seal on both of yours? I still got the factory red/orange seal in mine. And no problems at all at 2000 psi. And not a hint of leak down over long period of time. And I would like to know if the factory seal will take 3000psi. Then you don’t have to do nothing to the 2240 but screw in the hi-pac. And then you have the black seals that come with the hi-pac as backups.

    But let me know when you get yours shoot’n. And if it matter’s pray’n for your wife.

    Got one of my better groups with my 2240 with the Disco barrel today. It was dead calm today. If you dropped a feather it went straight down.

    A .750” clover leaf group from the outside of the holes the pellets made and it was at at 50 yards. I was shooting 5 shot groups with it and my HW50s while my ShoeBox was filling up my buddy bottle. I went through 2 of the Benjamin buddy bottles today plus shooting the HW. Lots of pellets shot today.

    All the guns shot great today. I was happy. Especially after the crazy week I had at work.

    But you asked the other day about the 2240 and I may not of gave the correct answer when I posted the group size the 2240 made. I said it averaged 1.400”. I should of said on that particular day. And I should say (I have done better). The 2240 conversion will put out a decent group if the conditions are right and I’m having a good day. Anyway I thought I would let you know.

  26. Thought I would mention this also.

    I talked to Dave tonight with RAI that makes those adapters to fit the AR style stock on the 2240’s and such. He says he has some new style adapters for the 13xx and 22xx series guns. Also one that allows for a folding stock option. Which is kind of cool.

    But here’s his his new updated site if you haven’t checked it out in a while.

    I understand what you are saying about the moisture pack and pressurizing containers , but I have my doubts that the pack will stay in place when shooting and filling. So I am kind of up in the air about it, I think I will contact hi-pac to ask about them before I start using mine and you can leave it in yours for a test if you want to but I would rather know for sure. I am thinking more along the line that they are put in there to prevent rust while sitting on the shelf waiting to be sold. I have worked on a lot of air and hydraulic systems and have seen the dry pack in parts when packaged but have never been instructed to leave them in. Automotive A/C systems have a desiccant bag in the accumulator on GM vehicles to absorb moisture but the pellets are in a burlap type woven cloth bag and I have replaced many A/C compressors because the desiccant bag has ruptured and clogged up the compressor and orifice tube, condenser and evaporator and that is more or less equivalent to a hydraulic system in that it is pumping liquid and gas at low and high pressures through the system during operation.

    I don’t believe any other PCP air guns come with desiccant bags in the air cylinders from the factory, you have quite a few PCP guns and have you found any desiccant bags in their cylinders or read about them having them in the owner’s manuals. If they were packaged in cloth I might agree to leave then in but being in paper I am not willing to take the chance.

    I am going to go ahead and change the valve seal to the ones supplied just so I don’t have to worry about it later because the stock seal is held in by a rolled edge on the front of the valve that would make it difficult to replace with the valve in the gun tube without damaging the brass where the seal sits.

    I will keep you up to date.

      I emailed them last night and got a response this morning. I will quote their words.

      “Its a dryer pack, leave it in if you need it.”

      But if you don’t feel comfortable take it out. Your logic makes sense also because I havent seen them in other pcp’s. But I havent taken the air resivoir apart on my FX or Hatsan either so I cant say about them. But I’m still going to keep mine in just to see what happens. And I’m lazy. I don’t feel like taking it a part. Plus it doesn’t leak so I don’t want to mess with it.

      And I don’t see the dry packs being used for liquid. They had them in accumulators on car air conditioners? I never cut one open either so I didn’t know that. I thought the dry packs was only supposed to be for air not gases or liquid.

      Anyway So how close are you to having one going?

      • Gunfun
        Yes the big aluminum accumulators on the line coming out of the evaporator box on the firewall of GM vehicles had a desiccant bag inside of it to remove moisture from the refrigerant ( R-12/134A ) systems and those bags would rupture and contaminate the whole A/C system. there were several cars that I had to replace the evaporator, condenser, compressor, orifice tube and accumulators and then flush every line and hose in the system to clean out the pebbles from inside the bag.

        So I have took mine out just so it cannot rupture and distribute the stuff thru the gun and then require a total tear down to clean out all the pebbles.

        I actually just got my 2289 back together in its original style as a pump pistol, I had to make a trigger spring guide so it still has the light trigger and spot face the 12 inch barrel to accept my ice maker breech port seal setup and just getting ready to start putting my 22 cal 18 inch barrel hi-pac together. so hopefully by tomorrow evening it will be shooting. My kids are on there way backup with the grand kids from Florida so I don’t know how much I will get done today.

        I will let you know how the 22 cal turns out, then its on to the 177 that I have to modify the 853 barrel to work in the crosman steel breech. slowly but surely they will get done this week.


      • Gunfun
        I don’t know if my post got stuck in the time warp or what but here it is again.

        Yes GM vehicles have a desiccant bag inside the accumulators of their A/c systems and those heavy burlap type material bag do rupture and spread the pebbles thru the whole system which requires most times replacement of the compressor, condenser, evaporator, orifice tube and accumulator and a complete flushing if all the lines and hoses to get the pebbles out. I am leaving the packs out of mine as I don’t want to have to go back and tear them down to clean the pebbles out later when they rupture. if they were in cloth bag’s I would probably leave them in but they are just paper like the salt and pepper you get at fast food restaurants so I just don’t trust them not to rupture,

        I have completed my 2289 back to its original pistol setup and had to make a trigger spring guide to keep the trigger light and smooth and also spot face the barrel port to fit my 1/4 inch ice maker transfer port seal, so the 2289 pump pistol is together and shooting.

        Now I am starting on my 22 cal hi-pac with the 18 inch barrel and it should be done by tomorrow . The kids are on their way up from Florida bringing the grand kids back up to start school Wednesday. So I don’t know how much time I will get on it today ,but it will be done tomorrow.

        Then I will complete my 177 hi-pac when I go get the 853 barrel modified to fit the crosman steel breech. it will be done by the end of the week hopefully.

        I will keep you informed

  28. Hi B.B. Can you recommend a good rifle rest? I think you mentioned 1 (red plastic) in your 2013 Christmas gift list but I can’t find it, the list. (Might be a good idea to add “B.B.’s Christmas Gift Ideas” to the Categories list.) Thanks. Joe

  29. B.B.,
    The front sight on your 1077 looks just like the one on my AM77! Fiber optic element sprout wings? I figure if I ever pull the scope off it I’ll have a nice little peep. Til then,I got bigger fish to fry!


  30. Dear B.B. –

    Thank you for all your good work. I just re-read all four parts of your Crosman 1077 review. In Part 1 you suggest leaving the barrel alone. I installed a Delrin barrel stabilizer bushing. Was this a mistake. If so, how would you remedy it.



    • Ralph,

      Welcome to the blog.

      I make those recommendations because some readers think they have to do everything they read about on the internet. I am trying to discourage them. Many of them don’t have the skills to work on their own airguns.

      If you have shimmed the barrel and if it still works okay, I would just leave it as it is.
