Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

Thread-on muzzle devices give the tactical rifle shooter a variety of options for flash suppression to meet his exact needs. Precision CNC machined to exact tolerances from high-quality stainless steel alloy that withstands extreme heat and gas particle erosion, even after thousands of rounds. Stands up to the intense tempo of combat conditions without loss of performance. Easily replaces factory flash suppressor on military-configuration AR-15/M16/M4/AR-style .308 rifles with no permanent modifications to gun. Install on other assault rifles, semi-autos, and bolt actions with muzzle threaded to accept the device. Not only improves the performance and enhances the appearance of your rifle, but also provides a rock-solid mounting platform for SureFire Fast-Attach® sound suppressors. SFMB and SF3P models accept SureFire SOCOM Series Fast-Attach® suppressors only, not earlier model Fast-Attach suppressors. Each kit includes a set of varying-thickness crush washers for proper indexing.

Advanced design provides superior muzzle flash reduction to help conceal the shooter’s position and preserve night vision. Rugged stainless steel construction gives exceptional strength and durability, with a variety of styles to fit AR-type rifles and carbines in both 5.56/.223 and 7.62/.308, as well as other assault rifles, semi-autos, and bolt actions.
