B&T SRBS 556 Full Size – Full-Auto Ready with Backpressure Control
Built for extreme use on gas-driven rifles, the B&T SRBS 556 Full Size suppressor is ready for hard rounds and hot barrels. Whether you’re running an SBR or a standard AR15, this can keeps backpressure low and reliability high. The low backpressure baffle architecture reduces gas-to-face blowback, limits bolt speed increases, and enhances system life under stress.
Manufactured using 3D laser bed fusion and forged from Inconel 718, the SRBS is fully weldless for lighter weight and fewer failure points. Its advanced baffle geometry minimizes flash, sound signature, and pressure wave propagation. This suppressor is HUB mount compatible, giving you the freedom to run it direct thread or switch to your favorite QD platform.
And for a limited time, every purchase includes a free tax stamp, automatically added to your order after checkout. Even if it’s on backorder, the stamp is locked in.

Fantastic can, eliminated the gas blowback on my mk18 and still quiet.
Joel Nadler –
I ran this suppressor on a Colt M4 in a multi-day Carbine Tactics class with Kris “Tanto” Paronto over the weekend and it ran flawlessly. My son (active Army: 101st) ran his Wilson Combat AR un-suppressed and wanted a suppressor by the end of the class. Great noise reduction, was easy to install, and with the crush washer stayed in place for around 1000 rounds of 5.56. Awesome suppressor! I am the one in lighter green and the suppressor is covered with a Cole-Tac suppressor cover.
P.S. I will never be able to rate a suppressor above 4 stars as $200 goes to the federal tax stamp.

10/10 recommended B&T is quickly becoming my favorite!
Joshua M –
This can is awesome great noise reduction and flash suppression.
Kyle R –
The SRBS Suppressor has completely exceeded my expectations. The backpressure is impressively low, with only a slight change in the ejection pattern from 3:00 to about 2:30. Even with 40 rounds fired rapidly, there was no gas blowback to the face—an issue I’ve encountered with other suppressors.
What really stands out is the heat management. After putting 70 rounds through it rapidly, the suppressor was still cool enough to touch within five minutes, which I believe is thanks to the Inconel construction. Inconel is putting in work!
There was a minimal “fireball” effect when firing in the dark, but from what I’ve read, that’s normal for the first few hundred rounds. Overall, I’m extremely satisfied and plan to use this suppressor exclusively from now on. The difference in sound suppression is incredible—no more ear-splitting bangs!
Highly recommended.

Although I’m relatively new to suppressor use, the exceptional quality of this item is immediately apparent. It is sumptuously smooth, reduces recoil, diminishes signature to marginal zero, and most impressively, has almost NO appreciable impact on back pressure. My somewhat gassy little baby — an IWI Galil Gen II — was consistently ejecting at 3 o’clock, and threw no fumes back in my face. This can is my number one choice for my higher gas guns, or any gun, really.
And as always, Silencer Shop was spectacular in offering, selling, and executing transfer of the piece. Thank you!

Suppressor is great, just a bummer I had to wait 3 months even when using the digital kiosk
Jordan Heater –
Very little gas to the face on MK18 and ejection pattern was at the 3 o’clock. I put the SF QD hub mount on it and it works flawlessly (just a bit long). Sound is good, can shoot without ears for a short period. I didn’t notice any muzzle flash with the 10.3. Solid flow through can for less than the competition. And the tax stamp was free through silencer shop.
Jeremiah V –
Great suppressor. Really makes shooting 5.56 pleasant. Don’t know what else to say…..it just works.
Branden R –
Phenomenal suppressor, does have a little bit of weight to it but on my mk18 it sits right at home. Crazy quiet! I’ll be ordering a 762 model soon enough!
Nick –
This can is incredible. Sound suppression is excellent, back pressure is minimal, and the design appears quite robust. A Titanium version will be great for low round count usage but I plan to abuse this.
I was a little concerned about bulk initially but given the performance I can’t fault it. With a Keymo adapter installed it sits at 17.3 ounces. Plenty of clearance before the first baffle for the longer NOX on one of my rifles.
While it feels like the cost of most suppressors should be lower, I get that it’s a strange marketplace. With the free stamp promo this is the best deal out there on flow through cans in my opinion.
Unless you specificallt need a Titanium 556 high flow can right now, I don’t detect any way the SRBS isn’t superior to the others on the market.
Donald A –
I’m so glad this product came to market. A budget priced suppressor with no barrel length restrictions is just what I was needing for my 7.5″ braced pistol/SBR. As expected, it is still not at hearing safe levels but it sure brings the muzzle report down to very tolerable from painful when used at an indoor range. Though on the heavy side compared to titanium units, the firearm doesn’t feel muzzle heavy or unbalanced when shouldered. My opinion might be different for a 16″ or 18″ barrel. I just don’t know yet. It heats up quick and cools down slow, so I suggest getting some sort of wrap to put on it for transport after your range day fun is done.
Peter Baylinson –
Excellent suppressor, easy to mount and use.
Dillon L –
Bought it for use on a DD mk18. I put about 100 rounds through it the first weekend and it sounded great and I had no issues with gas to the face
Fernando P –
My first suppressor and I absolutely loved it.
The process with silencershop and west coast pawn was incredibly fantastic as well.
I think B&T has a great product here. sound suppression was good but gas to the face was almost none. Extremely pleased.
Jacob K –
You can tell a lot of research when into the engineering of this. It does what it is supposed to do.
Eric T –
Quality is great, and sounds awesome. I was able to get the included tax stamp as well which makes this one of the best value for dollar in my opinion.
Adam S –
So far so GREAT. I put this on my DD Ml18 RIII without any muzzle device, and it works like a dream. Tone is excellent, no difference in shot placement, put over 70rnds through it day 1 and couldn’t be more pleased with the performance. Also got mine with a free tax stamp so that was a big plus. Gets hot after quickly, but seemed to cool down quickly too.
Brandon G –
Installed on 11.5″ SBR. Excellent suppressor, no idea what the actual sound reduction is in my case, but it definitely does not ring my ears (a few shots without ear-pro). Virtually 0 muzzle flash after 1st round, and as a lefty, the reduced backpressure is appreciated for limiting gas in my face. Unit was lighter than anticipated once mounted. 0 disappointments or regrets.
My LGS was fantastic as always.
Michael B –
Excellent quality.
Laree Weeks –
This was the first B&T suppressor I purchased and I am very happy with it. The price included the stamp and the process was very smooth. I will continue to purchase B&T products and products from the silencer shop.
Brandon Adams –
Awesome can. Can’t wait to send some rounds through it.
Dwayne L –
Very good product
