Solid suppressor mount by Chris, Verified Owner, April 9, 2026

Awesome muzzle brake by Mike, Verified Owner, November 29, 2021
This muzzle brake works with the surefire warden. It can bring a 14.5" barrel to over 16" with p/w. Does a great job negating recoil. Standing next to brake, it pushes you like a nudge, add a couple feet and nothing. Standing behind shooters right/le...
