The SureFire Muzzle Brake features offset porting which delivers greatly reduced recoil impulse and muzzle rise, so the weapon tracks straight back to keep you on target for faster shot-to-shot recovery. It is precision machined from U.S. mill-certified heat-treated stainless steel with high-precision single-point cut barrel threads, pilot holes for tuning of muzzle brake and to pin-and-weld to rifle barrel as needed. The muzzle brake has a DLC coating, Labyrinth seal, and serves as rock-solid mounting adapter for SureFire SOCOM Series sound suppressors. NOTE: SureFire SOCOM Series Fast-Attach sound suppressors and current-model muzzle brake/suppressor adapters and flash hider/suppressor adapters are not compatible with previous SureFire Fast-Attach sound suppressors, muzzle brakes, or flash hiders.
