Ammo .22-caliber Lightweight Disco Double: Part 2

.22-caliber Lightweight Disco Double: Part 2

by Tom Gaylord, a.k.a. B.B. Pelletier

Part 1

Disco Double new stock
The Lightweight Disco Double in its new stock looks striking!

I’d planned to report on the velocity of the Lightweight Disco Double today and, as good fortune would have it, the new stock arrived yesterday! So, I installed it and took a photo for you to see. I think it looks fabulous!

This stock was made by Normand Morin who has a website at Discos R Us. The wood grain is a very striking brown tone that’s finished shiny. The inletting is perfect for my rifle, and it dropped in with a tight fit. I like it even better than the walnut stock the rifle was shipped with. If you want to dress up your Disco, take a look at what this man can do for you.

Isn’t it ironic that I reported on the $100 PCP yesterday, and today I’m looking at the Disco Double? That wasn’t planned; but since it worked out, I’m sure you’ll draw some comparisons from the contrast of the 2 rifles.

First shots
I saved these first shots just for you! This is the first time I have fired the rifle since it arrived. I figured Crosman Premier lites could do the honors since the rifle is basically a Benjamin Discovery. At this time, I have not yet installed the TKO muzzlebrake, so the sound is what you would hear from a factory Discovery.

The needle on the rifle’s built-in pressure gauge was reading just below the 2,000 psi mark, which is the edge of the green zone for air. There’s a separate green zone for CO2 on the gauge, but it doesn’t really do much because a CO2 fill never goes above the pressure of the gas at whatever temperature the gun is at when it’s filled. In other words, CO2 pressure isn’t determined by the fill — it’s determined by the ambient temperature.

Here’s the first string I fired:

690      739          736
709      748          —
707      757          —
718      750          715
726      757         729
720      745         724
732      744         714
728      742         716
735      753          713
729      742         701
723      754        STOP
737      742
743      746
733      741
733      742
742      744
737      745
741      734
747      722
745      738

After examining the shot string, I concluded that the reservoir pressure was slightly too high when I began shooting, so I filled it to a slightly lower pressure (on the rifle’s built-in gauge) and fired 5 more times. That gave me the following velocities:


At the end of these 5 shots the on-board gauge read 1,900 psi. That looks like the right pressure to me.

Disco Double top of the fill
This is as high as the fill level will go for the first shot to be in the correct velocity range.

Disco Double end of fill
When the rifle falls off the power curve, this is where the needle sits.

More Disco Double features
I told you in Part 1 that this rifle has too many features to cover in just a single report. Two more of them are the stainless steel male Foster quick-disconnect fitting that’s used as a fill nipple. Lloyd has machined it into the end cap of the lower reservoir tube and covers it with a black plastic cap.

There’s also a special barrel band he can provide that has a dovetail on the bottom for the attachment of a bipod. That looks particularly handy, and I’m thinking of doing just that.

Disco Double fill nipple
The fill nipple is stainless steel and on the bottom tube.

Disco Double barrel hanger anchor
Lloyd makes this custom barrel band, which has an anchor point for a bipod on the bottom.

Analysis of the velocity numbers
Now that I have a good first string on record, let’s see what it means. These numbers seem on the low side, though I did tell Lloyd that I wanted maximum shots over anything else.

Lloyd sent me several spreadsheets with his own test velocities that I’ll now compare to mine. Then, we can select a good performance curve for the rifle.

OH, NO!!!
What did I do?
Dear readers, I just consulted the velocity spreadsheet Lloyd sent me and discovered that he was getting velocities in this rifle in the mid-800s, also using Crosman Premiers. But I saw right away what he was doing differently.

HE WAS USING .22-CALIBER PREMIERS, where I’d been shooting the much-harder-to-control .177 Premier lites. Apparently, this Disco Double is special. Not only does it get a lot of shots, it also shoots .177 pellets in the same barrel as .22 pellets!

I swear I’m telling the you the truth, just as it happened! When I made my “discovery,” I dropped a .177 Premier pellet down the muzzle of the gun and noticed it fell all the way down.

Yes, friends, B.B. Pelletier has done it once again. I’ll now give you 5 minutes to draw a crowd for my public humiliation.

I didn’t plan for this report to go this way, but I can’t write stuff this funny when I try. So, have a great weekend at my expense, and on Monday I’ll return with some different velocity numbers. These will be obtained with the .22-caliber Premiers that probably work much better in this gun.

    • DryCreekRob,

      Yeah, I wasn’t real pleased when I saw what I had done. But things like this really do happen and if we don’t acknowledge them we subtract from our lives just a little.

      It’s actually funny. I was all prepared to launch into a lengthy explanation of the power curve and how I would have selected the velocities I thought were good, and then I realized that it didn’t matter.


  1. BB Oh BB

    You don’t know how glad I am that you made this wonderful mistake. I think you just proved that a pellet could go down a rifled barrel at a reasonable velocity with a lower pressure. 🙂

    And I’m with John E. Can you shoot a group of the .177 caliber pellets just for the heck of it to see what they will do.

    I think I heard this before. But thank God for mistakes. And no telling if they will group good but dog gone BB now I want to know.

    And you see how the barrel band clamps are positioned on this gun. Please do that on the 100 dollar pcp before you do the 25 yard test ok. That’s how I have my clamps positioned on both of my Discovery’s. I think it will make things go better for the sake of the 100 dollar pcp gun.

    • GF1,

      Yeah, I even almost mentioned that in the report. Like RidgeRunner’s request for me to shoot Avanti BBs because their larger size will make them go faster in the C96.

      But no way am I going to try shooting a .177 pellet in a .22 barrel for accuracy. Haven’t I done enough experiments like that with my Nelson Lewis muzzleloader?


      • BB
        I’m sure you have done more tests then I can imagine. So All I can do is trust you. And even more now that you admit your mistakes so openly.

        You could of covered that one up very easy and we would of never known.

    • RR,

      Thanks. I know I’m not alone in making blunders like this, but when the bit is in my mouth and I’m pulling the cart it’s a real shock to discover a major blunder like this. Kind of like Cindy Crawford all dressed up and looking pretty but with 2 moles instead of just one. And then one of them starts to move!


  2. If only the news and other blogs were delivered with the same integrity as you have. Your credibility and honesty just went up by a factor of 10 in my book. And it was pretty high to begin with. Thank you!

  3. Don’t feel so bad B.B. It’s what makes us human!

    I mounted a new scope on one of my pistols just last summer. Had everything all lined up and went out in the back yard to try it out. I couldn’t understand why the target seemed so far away; I was ready to pack it up and ship it back as defective. It was only when I went to adjust the windage and elevation turrets that I discovered I had mounted it backwards!

  4. BB,
    That is hilarious! It is reassuring to know that we all have those, “I can’t believe I did that,” moments. Thanks for being generous enough to give us a good chuckle at your expense.

  5. BB,
    One of the things I appreciate about your blog is that you shoot what you get, report what you do, and don’t white wash your mistakes. I point this out to people who think that you are just a salesman for Pyramyd. If anyone read your blog for very long they would see that you are honest to a fault in what you report.

    I bought a left handed USFT Hunter from Arnold Smith at Malvern. I assumed it was a .177 and went out and tested it with .177 pellets. I didn’t have a scope on it and doesn’t have open sights so I wasn’t trying to hit anything. The gun shot, had a sweet trigger, and felt good and I bought it. When I got home I installed a scope and tried to sight it in. I couldn’t keep pellets on a sheet of paper at 10 yards. I am slow but I figured out that it had a 20 caliber barrel. I was fine with that. I e-mailed Arnold and he hadn’t shot it since it was a lefty and he thought it was a .177 also. Anyway, I landed up with a very rare 20 cal USFT Hunter.

    Have a good weekend guys,

    David Enoch

  6. B.B.,

    I always look forward to your Friday blogs. I never know what to expect!

    I’ve done things like that, too. Every Soldier knows “headspace and timing” is a bigger problem for people than for weapons.

    I once found a deformed .308 Winchester case in a deer blind. The case shoulders and neck were blown out- as if it had been fired from a 30-06 length chamber. It must have made a good story, if the hunter ever realized what they had done.

    Would a standard Discovery benefit from having a muzzle barrelband similar to a Disco Double? The barrel is thin and flexible, and I’ve wondered if normal use would bend the barrel and move the point of impact.

    Hope everyone has a good weekend,


    • RB,

      I don’t know about the extra barrel band. Some say a free-floated barrel is the most accurate, while others say it’s best to clamp them down tight. I think in the case of the Discovery, an extra barrel band couldn’t hurt.


  7. Thanks for the grin, B.B. I have a very special chuckle that seems to come out when something like this happens to someone else. There’s a little voice behind it that always reminds me, “yuk it up, my friend, and remember the motorcyclist’s mantra: there are two kinds of motorcyclists–those who have laid a bike down, and those who will.” Ironically, maybe, that makes it even more enjoyable.

    And I always consider it a plug for humanity when someone is willing to don the dunce cap of his own free will, and use the bullhorn to say, “That’s right, here you go, right here.”

    Wouldn’t we be boring creatures, without that?

      • Many, many years ago I took my first street bike, a Yamaha RD 350 two stroke, to a car wash to clean it up a little. Wanded if off real nice and wiped the seat and metal dry. Drove it out of the carwash and leaned it over a little to turn down the street. Boom! Laid it right over flat onto the pavement. Wet, soapy sidewalls do not grip worth a darn! Oops!

        • Akin to the pilot saying “There are two kinds of pilots, those who have landed gear up and those who will land gear up” After 1100 hours of flying I moved into the first group. Fortunately it was in a glider on a grass airfield. Lift the ship up, extend the gear, clean the grass smears off the fiberglass and good as new. Much less expensive than the twin engine Piper that did the same thing on asphalt at another nearby airport this summer. I won’t go into the fate of my RZ-350 because I don’t want to provide any more anti-motorcycle ammo:-)

          I am surprised the .177’s shot that well out of a .22 barrel. I would have thought the velocity would have been way down and they would have wobbled enough to perhaps hit the chrony.

  8. BB,

    been there, done that – and now I welcome you to the club! Just thing of the consternation you would have faced if you conducted the accuracy test and couldn’t figure out at first why the pellets were giving you a 3 foot group. That’s how I found out 🙂

      • lloyd
        That’s a good point. Did you give BB the instructions that Mike wraps around the muzzle brakes when he ships them.

        Very ,very important to rotate the muzzle brake to a spot so the pellets wont clip the brake before you lock it down to the barrel with the set screws.

        Two bad things happen. It will mess the brake up because Mike reams the holes to a pretty close tolerance to the diameter of the pellet caliber. And if it clips it bad enough you will probably end up not getting it to work right.

        But on the other hand this is the second thing. You will definitely not get the accuracy from your gun that you are use to if the pellet is clipping the brake. Even if it is just a very little bit. So you can tell within only a few shots if you need to rotate the brake.

        I just wanted to bring this up because I usually request Mike to do a tight ream on my brakes I get from him. So its a little trickier to get the brake located right.

        • GF1,

          Okay, you and Lloyd now have my attention! I don’t like silencers that have the possibility of clipping the pellets. I had a Daystate silencer once that did that and it took me a long time to figure out what was happening, because the clip was slight and intermittent! I finally took it off the rifle and just shot without it.


          • BB
            I got to say this right away. The last part of my comment I mention that I have Mike do a tight ream for me. What he does is uses a little smaller diameter reamer than he would in his normal muzzle brakes. Plus I have got brakes from him up to 10 inches long and with that tight ream. So the longer the brake the more critical it is to take care.

            His normal production models are usually around 6 inches long and the diameter of the hole that the pellet goes through is a bigger diameter. I have had I’m sure at least 5 of his normal brakes through out time on my guns and just put them on with no problem.

            The reason I made the comment was so you would be aware of what could happen. And by the way the 10 inch tight ream brake I could rotate the brake around in one direction and shoot at different points and I made it about 7/8 th’s around with out it clipping. In other words it would clip in just that one little area very slightly. So in other words I could rotate it to all those other places with no problem. All the other normal production brakes could be rotated all the way around and shot in any position with out it clipping. So if it is a normal production model I don’t see you having any problem. I think Mike takes that in to account when he makes them so it does work out easier for somebody to set.

            I have tryed other brand brakes and air strippers and the TKO works the best and is the easiest to set up on the gun in my opinion.

            And these are from my experience’s with the brakes. Mike or lloyd could have something to add to this and they are more than welcome to correct me if I’m wrong.

            • GunFun1
              I am wondering about your term muzzle brakes. Are you taking about what are commonly referred to as silencers, or something that aids cocking at the end of a break barrel rifle or pistol? I am also curious as to the reason for such tight tolerances as opposed to Lloyd’s regular tolerance model. I admire your curiosity and dedication to the sport of air guns.

              • Don’t know about you-all, but to me a muzzle break is something meant to reduce muzzle flip on firing. A silencer is NOT it, except by accident. Ported muzzle breaks are actually noisier as they direct expanding gases out the top/sides/whereever instead of pushing directly out the end. A heavy inertial weight on the end of the muzzle would also apply (this is how silencers “accidentally” apply — they add mass that reduces muzzle flip).

                • I think of a muzzle break in the same way. I think of a muzzle break as open porting not baffeling that can both reduce recoil and tune barrel vibration to increase accuracy. With the draw back being a louder heard report. But that’s coming from firearms not air rifles.

              • Titus
                First off thanks for the comment and all I can say is I like air gun shooting. Always have liked air gun shooting more than firearms.

                And the last part of Wulfraed’s comment probably is what would apply to the TKO muzzle brakes.

                And Mike Teihen is the one that makes the TKO muzzle brakes. Not lloyd. But when I call them a muzzle brake (TKO muzzlbrake) I’m using the name that Mike has given them on his web site.

                All I can say is that’s a very controversial subject. Muzzle brakes, air strippers, flash suppressors moderators. Then add airguns to the mix. Supposedly certain rules mean different things if its a airgun or a fire arm. But maybe that is a good thing. It sounds like the rule makers are a little more confused about the subject than I am. But thanks again for the good comment.

                Here is his website if that may help.


          • Yes, muzzle brake is certainly a euphemism often used to stay away from any hot button powder burner terminology. These are sometimes called a TKO LDC, for lead dust collector. An accurate, although incomplete, description.
            The one I sent to BB came in a trade to me so I didn’t have any instructions. I tried it on the barrel of this particular gun and it is a nice snug fit, with really no play for set screw adjustment.

            BB, please check to make sure it is not a .177 version before shooting any .22 pellets thru it. That would certainly be worth another chuckle or two in this series.

              • I just noticed this in Lloyd’s comment.

                The TKO muzzle brake is supposed to be a tight slip fit to the barrel. The setscrews in the muzzle are not there to locate the muzzle brake. They are there to secure the brake to the barrel after you have the brake rotated to the correct location. Then you lightly touch the setscrews down to contact the barrel and keep it fixed to that position.

                I’m sure it was probably understood that way already but I wanted to make sure you weren’t trying to pull the brake into position with the set screws. That would be bad.

  9. An average guy would have scrapped the article, so you are above average. We will have to start calling you BB Mushroom because you’re such a “fun guy” (…fungi, get it?…)

  10. This is interesting. I’d like to see what this does with a boss max flow valve, power adjuster, and a stainless steel extended probe bolt. Then I’d know if my power upgrades were worth what I put into the disco. I also found that a thumbhole stock makes this look absolutely amazing. I’m doing a bit more to mine than just that so it won’t have any resemblance to a disco when I’m finished, but you get the general Idea here.

  11. Man, BB! Great laugh! I can’t count how many times I’ve done that very same thing. Sitting there scratching my head as to why my gun is suddenly shooting with no accuracy and a “different” sound. If the matter can goof up, then there’s hope for me!


  12. While it’s not exactly the same thing, I can’t help but be reminded of certain political types who explore the concept of “Plausible Deniability.” Funny how that never seems to work out for the now credibility-challenged author of the attempt.
    Just as remarkable is the the increase of credibility by one who’s willing to admit to a…shall we say,…middle-aged moment?
    B. B. Rocks.
    (By the way, I hear that opening on the Comedy Channel is still available.)

    • lioniii,
      That’s a good question about the weight of one big tube verses two smaller tubes, and the answer might surprise you. To maintain the proper strength and safety factor for filling these tubes to 2,000 psi and higher, the wall thickness must become thicker as the diameter of the tube increases. The tubes on BBs gun are .875″ in dia and have a wall thickness of .095, and a safety factor at 3,000 psi of 3.6 to 1 (at yield strength). A single tube to hold twice the amount of air at the same safety factor would be 1.310″ in dia with a .140 wall. And guess what, it weighs exactly the same as two of the smaller tubes.

      So it’s a wash. Two small tubes or one large tube weigh the same.

      To get a lighter weight tube you have to find a material that weighs less and/or has higher strength.

        • Howdy Fred D. Geez bud, ya just scared the bejeebers outa me, ya sounded just like my 2nd wife!?! Always lose count after five, switchin’ ta the other hand always screws me up. Truth is, I’ve never really been married. Every few years I just find a woman who hates my guts, then give her half of everything I own. B.t.w. just cuz we’re pals, gonna let ya in on a secret, lean in close, gotta type real quiet, don’t want the rest of the gang ta hear this. 75% of the stuff I throw out here is about half true, the other 50% is total Bullschtuff. Easiest way ta tell the difference is if my lips ain’t movin’ I’m tellin’ the truth!?! Hope that cleared it up. Shoot/ride safe,

            • Howdy Ben, So that’s where he went, threw one of my deadly, patented triple wedgie with a half twist on him & haven’t seen him since. We used ta be real close, went ta different high schools together. Tell him howdy for me.

            • Howdy Ms. Edith, I thought name callin’ was strictly forbidden!?! I wuz gonna be a politician when I got a little older, but then realized that when ya get ta be my age, it’s too hard ta remember who ya told what to, so now I limit my drinkin’ & lyin’ ta only on days that end in “Y”

              • OK now. Everyone quick picking on the Beaz. Beazer, I suspect you’ve been married to the same woman for 40 years and ride a Goldwing when the Hog doesn’t start. As far as I’m concerned, if you shoot air rifles and ride bikes, you can’t do anything wrong!

                Fred DPRoNJ

                • Fred D. My Liars Annonymouse group meetings are really helpin’ alot…unless I go fishin’ or shootin’ then all bets are off. I really have never been married, just played house w/a few. Do have a couple pairs of socks & my lucky Roy Rogers Lil’ Buckaroo underwear that I’ve had for over 40 years. The current future ex girlfriend has hung around for about 6 years which I think is pretty close ta a record. She just might be a keeper. Got my first H-D in ’78 & have bled black & orange ever since. Will tell ya that after 43 years of legally ridin’ on the street, I finally went down, 1/15/14. I did a perfectly executed stop, drop & roll, so I’m ok, but the bike suffered $8200. in damage as the frame is cracked & has ta be replaced. 6 weeks before I’m back in the saddle. Guy who left turned me ran, but a witness chased him down & got his plate #. Once I get through all this insurance BS, got no wheels, so should get alot of quality time w/the T-reX. Shoot/ride safe & have a great weekend.

                  • Harley’s do have decent brakes, buts that’s about all I’ll give them. When I compare them to the jap bikes I was forced to buy when I was young and broke they seem over priced, under powered, unreliable and not much of a pleasure to ride. Why don’t they go to a hydraulic clutch and inverted fork front suspension. That should remedy my biggest to complaints with the way they ride.

  13. B.B., does this mean we’ll be a velocity test on .20 cal with the double disco as well? May have a new marketing idea there. A double Disco triple Cal. hat is a .177, .20 or .22 cal without a barrel switch! Just kidding. Nice to know I’m not the only one to “goof up” once in a while.
    On a serious note, How many shots would you guess you’d get if the Double Disco were filled with C02? Not asking you to try it, just wondering. Bet it would be a heck of a lot! Bradly

  14. B.B.,

    Kudos to you for going ahead and actually sharing this with us. Couldn’t have been a better, albeit unusable, Friday report. The older I get the more boneheaded mistakes like this I make. But we have to laugh at ourselves! What else you gonna do?


  15. Hello B.B.,
    I just put a 5 inch TKO LDC on my 177 Discovery. It made it my favorite air rifle to shoot again. The before and after installation results are amazing. Great product!

  16. Speaking of mistakes: a friend and I installed a new barrel on a Colt revolver he’d chased. About the time we finished i noticed that the barrel he’d bought was .32 caliber, whereas the revolver was .38 special. I’m sure we’d have remembered that mistake had we lived!

  17. Jim, as long as you brought up the Arisaka story, here is what happened– The NRA received an Arisaka from a man who wanted to know why it kicked so hard when he fired it. The NRA found that it was a 6.5mm type 38 rifle. the owner had rechambered it to 30-06! When the NRA asked him how he was able to get the chamber reamer into a 6.5 bore, he replied that he had cut off the pilot (.30 cal))! The NrA test fired this rifle several times. It swaged the .308 bullet down to 6.5 mm. The headspace did not change, and the NRA stated that they could not think of a more severe test for a rifle and action. They also said that it was a good thing that the owner did not fire armor piercing ammo in this rifle.I do not know where the rifle is now, or if the NRA tried firing ap ammo in it. PO Ackleys destruction tests have confirmed the strength of Arisaka rifles. Ed

    • Yes, my M1 Garand gunsmith, Clint Fowler tells me that the M1 and the Arisaka have the strongest actions of all the WWII military rifles. The M1 was able to withstand something called a Blue Pill load that generated 100,000 psi.


  18. <snicker>

    When can we expect the accuracy test of the .177 pellets in this beast <G>

    Oh, BTW: Maybe you can run cross country and use it to ensure the ground hog doesn’t predict more winter…

  19. That is too funny. I did notice that the double Disco has two barrel bands securing the barrel, while the standard Discovery has only one. The 100 buck PCP had a free floating barrel until the high tech tape was used and the standard Discovery barrel is mostly free floating. I remember the article where someone actually glued the front part of a standard Discovery barrel to fix it in place. I do wonder how much any of this affects accuracy–if at all. My hunch is that one is better off attaching the barrel at only one point provided the barrel is sufficiently rigid. I don’t think barrel harmonics would be much of an issue with these rifles, but deformation of the reservoir tubes due to pressure level and temp changes may slightly change the point of aim. All I can say is that my hundred dollar standard Discovery is so accurate as delivered that I am afraid to change anything. The double Disco with the custom stock sure is pretty to look at so I can understand the temptation.

    • ray
      How funny could that be. Your comment wasn’t up yet when I was writing my comment.

      So here is how my comment would of been. I don’t know which way is really the better as for as clamping or free floating the barrel goes. I have guns that have barrels both ways. But there is one point that could be made. I would rather try to keep the barrel center line and the scope center line parallel if at all possible. And I don’t even want to say what I have done to the barrels on my Marauders and 1720T. All I can say is they are quieter and I haven’t added any device to the guns and the barrels do now truly float. I will leave it at that.

      And I agree that sure is a pretty stock to look at on that Double Disco. 🙂

  20. I have an off topic curious question. I spent the last week cutting the filament off every fiber optic sight I had around. A few of the guns have a sight picture that is better than I would’ve thought with an open circle of daylight in the front post with a notched rear sight. I’m wondering if a rear peep was substituted would that same hole in the front post affect centering the sight? I’ll try it soon, I’ve just got nagging curiosity.

    • I did the same thing with my remmington vantage and the accuracy went from nickle to dime sized groups at ten meters. The fiber optic pin was mounted between two ‘hoops’ on the front sight, so i cut down the back one, leaving the front for a ring sight as you mentioned. Of course the weather started getting a bit chilly and i had to start working again late this fall si haven’t had a chance to sit down and test it at 25yd. This week should be warm enough(mid 40’s) to spend some time in the back yard shooting at 25yds. I hope.

  21. BB thank you for the kind words about your new stock and mentioning Discos R Us

    While reading about your shooting .177 caliber pellets in the new .22 caliber Disco I looked over in the corner of my shop at a few stocks sitting there waiting to become kindling for the wood stove just because of simple mistakes like reading the ruler wrong. So I guess we all have those moments, the main thing is let’s hope that they are few and far between.

    Enjoy the Disco DT as Lloyd has a great product.

    • Norm,

      God bless you! I don’t know if you have ever read this blog, but I am a wood butcher! I once “relieved” a Bronco stock for clearance on the side slide of a rear peep sight, and the work looked like it was done by a rabid beaver!


      These guys will never let me forget it. I was advised not to quit my day job.

      You, on the other hand, turn out gorgeous work. Every time I pick up the rifle that stock feels warm in my hands. That is the sign of a well-proportioned stock!

      Thank you, and keep up the good work!


  22. You thought a .22 rifle was .177? Heh heh. I feel better about shooting two pellets out the barrel of my IZH61 last night. Some dumb mistakes I’m just resigned to.


  23. Hello Fellow Airgunners
    I sure like the looks of your new double tube Disco. I have never been enamoured with the Korean double air tube models. They have a bulky and unwieldily appearance to my eyes. I realize you need a lot of air to push a .45 or .50 cal projectile at a respectable hunting velocity, and these air guns have quite a popular following. I like my air guns to look good as well as shoot good and not be soly utilitarian. Lloyd seems to have eliminated the bulky look by being able to use smaller tubes with the Disco. I suppose this is possible for the smaller .177 or .22 cal where less air is needed for a decent velocity. I also want to comment on your trigger guard. It gives the gun a classic look, sort of like a classic musket.

  24. Hello, Fellow airgunners! First time poster so, be gentle. A friend & I were talking Benji’s the other day at the scrap yard. Turns out he has a 3120 he no longer cares to own?! He says it won’t hold/build pressure. I’ve been through my 392PA, and a few 760 Pumpmasters. With the potential cost to return it to working order running $50 to $70 it kinda feels like a gamble! Condition would of course need to be on the Fair to Good part of the scale, investment wise. In your opinion, what do you think would be a fair price range for us to begin the resurrection? I would want it more for shooting and hunting, so it must be repaired. Haven’t seen it yet. Any input is welcome. (Hope it has a rifled barrel!)

    • Reb,

      A Benjamin 3120 is a rare airgun. In working condition and average shape it would be worth $150-200. It shoots .22 caliber lead balls, only.

      Welcome to the blog and consider getting a Blue Book of Airguns that has this sort of information.


    • Any rifle/pistol I ever bought or rebuilt, I carefully check the bore to see how good it is and then I go from there. If the rifling is good, then how is the action? How does the steel look, then the stock…

  25. I am going to buy a Daisy m14 co2 rifle. I am going to shoot pellets only through this rifle. Should I shoot bb ,s through it to polish the bore (for greater accuracy with the pellets)? If so , how many shots with bb,s will it take? Is there any evidence that shows loss of accuracy when bb,s are used in pellet-bb guns? Thanks, Ed

    • Ed,

      No, shooting BBs will not polish the bore of your rifle. Just shoot pellets.

      Regarding your question concerning loss of accuracy when BBs are fired in guns that also use pellets, no, there is no concrete evidence. BBs are just so much poorer than pellets in the accuracy department that it makes no sense to shoot them, unless you are going for something other than hitting your target.


  26. I wasn’t going to post this then I thought about it some more because maybe somebody would be interested in trying this.

    This is something I have been doing with the shrouds on the 1720T, Marauder pistol and rifles. It uses all the stock parts and you don’t have to modify anything. And all you have is the extra cost of a spring. Yep all you have to do is add a spring.

    You take and unscrew the shroud off the adapter that is on the barrel by the receiver. Leave the baffles in the barrel and slide a spring that is almost the same outside diameter as the inside diameter of the shroud and have the spring be 6″ long. Now all you do is loosen the set screw up and slide the adapter forward 6″ and lock it down. Then screw the shroud back on until it stops snug on the adapter. The spring holds the baffles forward taking up the space between the barrel and the baffles. And the barrel does truly float now. The gun is way quieter now this way and you can make it longer or shorter by changing how long the spring is. And by moving the factory adapter forward or back the distance of the spring.

    I didn’t want to post about the shroud trick that I do because of maybe taking the sales away from people making the add on devices but its so simple. And it still keeps the gun in its original form but you could use the excuse that you are just adjusting the shroud for barrel harmonics if you will. Or I guess we could call it that instead of the S word if you know what I mean.

    Just thought maybe somebody would be interested.
