Beeman QB78 Suppressor Kit


  • Designed and 3D Printed in ABS in the US by a veteran/family-owned business

  • Easy install. Doesn’t require any modification to the stock airgun
  • FREE SHIPPING to anywhere in the USA. Ships same or next business day via USPS

****PLEASE READ THE FULL DESCRIPTION BELOW!****

PLEASE NOTE: Beeman offers these airguns in two barrel sizes. The only way to know what barrel size you have is to measure it, as far as I know. Please measure your barrel and select the size that will best fit your airgun. I don’t know how tight or loose Beeman’s tolerances are. If it is too tight you may need to sand or drill out the ID to get the fit you need. If you’re not comfortable with this please do not purchase. I’m just trying to provide a niche service at a great price.

This kit includes a threaded clamping adapter, suppressor, and thread protector. The suppressor adapter was designed for and tested on the Beeman QB78 Deluxe, but it may be compatible with some other airguns in the Beeman Power Series. The adapter doesn’t require any modifications to the airgun. It just slides onto the barrel and clamps on with two stainless steel socket cap screws and nuts. It uses the same threaded suppressor and air stripper as our Crosman 1077, M4-177, 880 and 13XX kits. The suppressor includes 7 cone-shaped internal baffles. If you’d like to shoot without the suppressor you can install the faux stripper as a thread protector.

You have the option to select the adapter only. The adapter will come with the thread protector, but no suppressor. You might select this option if you already have one of our UNI Suppressors and don’t mind using the same one on multiple airguns and want to save yourself some moneys!

To install:

  • Ensure adapter socket cap screws are loosened
  • Slide adapter onto barrel shroud while aligning slot with front sight post until bottomed out
  • Use an allen wrench to tighten the cap screws on the adapter
  • Thread on the suppressor or thread protector as desired

PLEASE NOTE: I used to make the suppressor with a larger opening than necessary to avoid any clipping issues, but have decided to tighten it up for maximum report suppression. This will increase the likelihood of pellet clipping. If the accuracy of your airgun is affected you may need to drill out your suppressor little by little until the accuracy is no longer affected. If you are not comfortable with this please do not purchase. But it’s not bad. The drill bit will self-align using the baffles like a pilot hole. Make sure you remove the suppressor from the airgun before you drill it out.

    Typical good quality from Buck Rail.
    I measured the barrel diameter per BR instructions and fit was acceptable. There was enough wobble when installed that caused clipping if the adapter was tilted up.
    My solution was a strip of tape on each side of the split and that eliminated the wobble. I’ve taken it off and on several times and it returns to POA consistently.
    The suppressor definitely eliminates the “snap” from the CO2 gun, and weight is under 2 ozs.
    I would rather have a “fatter”, shorter suppressor than the long, thin size.
    I’d like to see an adapter with 1/2 x 20 threads.

    I was using the QB78 suppressor on my .177 rifle. Unfortunately, it slipped and fell to the floor. The suppressor broke off at the receiver end of the adapter. I sent a message to Chris after I couldn't find an option to purchase just the suppressor. Chris sent me a message letting me know the breakage was covered and that he would send a replacement. Two days later it was in my mailbox. GREAT SERVICE!

    I bought this to put on my Beeman QB chief. Great gun, but way too loud to shoot in my backyard so it sat, what a shame. Then, came across this suppressor and wow, what a difference. Totally backyard friendly now!! When I put it on at first though it was shooting way off. In the description Terry put if you experience this you can use a drill to smooth out the suppressor bore. I did this, worked like a charm!! I got my QB Chief back in action because of this great little product!!

    I posted another review with a rating of 5 stars. I had a replacement suppressor come in after my previous one cracked. Around 500 or so shots later, the suppressor broke again. As I shot a pellet, I noticed it didn’t leave the barrel and I heard something rattling inside the gun, turns out the pellet hit something in the suppressor and fragmented inside of it. Everything was put on perfectly too. It’s a shame, I really liked the product but after two broken suppressors after not that much use… idk, maybe the third time’s the charm? Rating three stars because it did work, and the great customer service.

    I recently bought an extra QB78 suppressor adapter to install on my BEEMAN 1022 .177/.22 dual caliber air rifle. The first one worked great when used with the .177 barrel so I ordered one for the .22 cal barrel.

    While zeroing the .22 cal barrel with the second adapter, the threaded portion of the adapter unexpectedly snapped off.
    Oh no.
    I contacted Buck-Rail and Chris replied promptly,apologized for the failure, gave me zero hassles, and sent out a replacement at no cost to me right away.
    Now that is what I call standing behind your product !

    I originally purchased one 14mm adapter and suppressor for my BEEMAN Black Cub 1022 dual caliber .177/.22 rifle that comes with two separate barrels which you can switch out as desired. That unit was used on the .177 cal barrel installed on the rifle. I was very pleased with the performance of the QB78 suppressor and adapter that I just had to at least get another adapter so that I can easily switch out the suppressor from barrel to barrel.
    Again, Buck-Rail really scores high praise from me for yet another awesome product !

    Got the 14&15mm adapters with suppressors for Qb78 s and qb79. I broke both adapters within 30 minutes of receiving them. I have a habit of over tightening things. Couple tubes of jb weld later and they fit both guns perfectly. Adapters ain’t to perty to look at but their on and and doing their job. Can’t believe how quiet the guns are now. Also improved the accuracy at 20 yards on the qb78s from 1/2” to less than 1/4” the qb79 improved from 1/4” to 1/8” both shooting Crossman 7.9g match grade pellets. Thank y’all for making these things so affordable.

    Got a screamin' deal on a new BEEMAN Black Cub 1022 dual caliber .177/.22 springer recently. But even after cleaning the barrel and getting thru some dieseling, it still generates a loud pop.

    So off to Buck-Rail I go and decided that this QB78 suppressor and adapter would work. I measured my barrel and determined that one in 14mm would do the trick. Placed my order and couldn't wait to try it out.

    It arrived today and I immediately installed it. 14mm fits just snugly enough and after tightening the screws down a bit, got a wiggle-free fit. The first order of business was to do an A/B comparison without a suppressor and then with one.

    As expected the rifle's loud pop was still present. Once the suppressor was installed the sound of the spring piston being released & impact of the pellet was just about the only thing really noticed. The report was now a softer **poof** followed by the spring &sound of the pellet impacting the backstop .
    Once again yet another stellar Buck-Rail product!

    I wish I could give this product 10 stars. I was looking for a suppressor for my Benjamin Prowler break-barrel and wasn’t sure from the catalog what would fit. I emailed Chris and he was extremely helpful. I measured the barrel with calipers and it came in at 14.8mm, perfect for this kit.

    It fits perfectly, and the included thread protector in the style of an AR muzzle break is great. I did have a slight issue with clipping, so I drilled out the ID with a 5/16” bit and that resolved it. (Interestingly the closest 2-3 gates appear to be smaller in diameter than the farthest. Those were already a little larger than 5/16”). All 3 parts are very rigid, surprisingly so. I will say, be careful not to overtighten the Allen screws in the thread adapter. I added some Loctite to the threads and did just a 1/4 turn past hand tight.

    Sound suppression exceeded my expectations, especially given the crazy low price of this kit. The Prowler sounds like a .22 short out of the box, problematic given that I live in a dense residential neighborhood. With the suppressor it sounds a lot more like my old pump air rifle I had as a kid. Much more neighbor-friendly. Can’t support this product enough!

    Buck-Rail is awesome! I ordered the 15mm adapter for my Beeman QB-78s and didn't order the suppressor because I thought I had one that would fit the adapter but I was mistaken. Contacted BR and the next thing I know they mailed out the proper suppressor. Awesome customer service, all of my airgun collection whether it be the co2 Diana Chaser or Crosman 2240 or my pcp Air Venturi Avenger bullpup, Kral Puncher Breaker bullpup or a pump up gun like my Crosman 1377/1322's have BR products on them and they work and you can't beat the price. Whenever I'm looking for something BuckRail is the first place I look!

    My biggest concern with suppressors is a bad fit leading to clipping. So I was more than happy when I put the adapter onto my 15mm CZ200s barrel and it fit snug, with no play, even before I tightened the screws. Both the suppressor and the adapter are solid, strong, and look good.
    It’s hard to find quality products like this for such a reasonable price, thanks Buck Rail.

    This is a very versatile adapter/suppressor. I say that because I haven't actually used them on a Beeman QB78 but on other model air rifles. The 15mm adapter fit an old Brolin arms side cocker perfectly after removing the front sight ramp and the 14mm adapter fit a Beeman Kodiak barrel after removing the muzzle brake and using a small strip of 150 grit sand paper wrapped around a tube to enlarge the sleeve area slightly.
    As I said, very versatile for all (plain/sightless) barrels in the 13 - 16mm range.
    Might need to wrap the barrel end with plastic tape or sand the adapter sleeve area slightly.

    Bought this for my 2021 Beeman QB Chief in .22 caliber. It was much louder than my Gamo springer in .177. Even though I live a bit away from my neighbors, I still didn't like how loud the report was. Installation took a minute or two, and it made this thing much much quieter. I mainly only hear the mechanical action now, and not the air rush out the barrel. Before it was close to a centerfire .22. POW! I measured the DB level and it was around 92db without, and 82db with the suppressor. A 10db reduction is roughly half the noise level, so now I can plink away and not worry about upsetting my neighbors. Also the adapter includes a cool screw-on AR15 style muzzle brake. I looked inside the suppressor with a flashlight and saw there are V shaped cones in there which makes sense. Gonna experiment with adding material inside and maybe wrap it for more sound reduction. 

    So the adapter does not hit the cap under the barrel that covers the air inlet. Also I can still pump it up using my hand pump although the pump fitting hits the adapter a little. All in all the BEST addition I have ever purchased for any gun or air rifle for $20 (shipped). The plastic is pretty rigid. I have 3D printed before and this is no doubt made to last, much better printer than I used.

    My Crosman SSP–250 is finally “Backyard Quiet” & providing the accuracy I had come to expect from this awesome vintage pistol.
    IMO: One of the best engineered, designed & most accurate Air Pistols Crosman ever produced in their Sport Silhouette line (Comes Standard with a steel breach, frame & barrel.)

    I just installed one of these on a Beeman chief. Its the single shot 2000 psi rifle. I have to say that I am impressed by how much it quieted the gun. Now the biggest thing you hear is the hammer spring. Prior to using it the gun sounded very much like a 22 long rifle going off. I should not have been surprised by this because everything else I have bought from Terry has performed in much the same way. Once again Kudos to you Terry, and thanks for another great product.

    The adapter does not fit the QB78S. I tried to gently tap it on when it would not just slide on and it cracked, my fault should have just returned it.

    I loosened the screws all the way but when installing the adapter broke. I super glued it together and it will probably be ok as long as I don't bump it against something. It was very tight going on so I tried pushing and twisting it but it still broke.
