****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. Many customer have reported that this suppressor worked on their Chief. Also, many have reported that it doesn’t. I didn’t design it for the Chief. Do with that what you will.
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.
The only downside is the adapter. The first one sheared/broke at the thread/main body junction, three rounds after install. It looked like a printing error.
It was replaced promptly after an email to CHRIS.
The second had broken in a similar way after 15 rounds.
Number 3 on its way as of 11/5. I will be reinforcing this one with a 10mmOD x 6mmID carbon fiber rod internally, and epoxy on the outside.
Overall, the suppressor works, but the adapter needs reengineering.
I would advise to produce a solid version, without the sight cutout. Have the thickness increased 2-3mm, giving the suppressor a solid wall to butt against.
Good products, PHENOMENAL CUSTOMER SERVICE. I will continue to use 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.
fit the barrel like a glove along with the non tapered suppressor which by the way is awesome! All that you here now is the pellet hitting the trap! Now I will be able to shoot in my backyard and not disturb the neighbors!

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 !
A few days later was back plinkin' away !
Again, Buck-Rail really scores high praise from me for yet another awesome product !
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!
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!
suggest possibly threading inner barrel adapter with an 1/2 x 28 thread? 😁
It’s hard to find quality products like this for such a reasonable price, thanks Buck Rail.
The adapter fit perfect over my Barrel and the silencer really toned down the rapport. I had a problem with the threads on the adapter, contacted Chris and he responded within the day that he was shipping me out a new adapter. Their customer service is outstanding.
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.
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.)
Thanks again for a wonderful product that fulfilled my expectations … And, more!
