Questions & Answers
Which model will work on my Daniel defense 18” 6.8 spc barrel with a 5/8 x 24 thread? Expert Answer

Unfortunately, there is not a model that will work with the 6.8 caliber Daniel Defense barrel.

by Bethany Kopel, Gear Expert, December 11, 2020
My 10mm Stribog threading is 9/16 x 24. Will this muzzle device fit? Expert Answer

The SilencerCo ASR Muzzle Brake is not compatible with your Stribog as the 9/16x24 model will only accommodate a bullet with a max diameter of 0.311". 10mm has a bullet diameter of 0.400" and would strike the muzzle device.

Great product by BP, March 22, 2022
Great product. Fit and finish is perfect. Works amazingly on my .338 Lapua. The best way for me to run my Silencerco Omega 36M. This brake works as well if not better than the one that came on the rifle from the factory.

Silencer Co ASR Bravo Mount by Rhett, April 6, 2021
When combined with the “female” side of the mounting system, my Hybrid 46 can installs much quicker than a direct thread option. The ASR mount also doubles as a break when the can is not mounted; it does a respectable job of reducing felt recoil on ...

Clean Muzzle Brake by Grey, September 27, 2021
I bought this so that I can easily attach my SilencerCo Hybrid suppressor from weapon to weapon with the ASR system and it works perfectly. No hassle. Just be patient with the shims to get the brake ports facing exactly 3 and 9 o’clock.
