The Armaspec Fireball Compensating Muzzle Brake (Armaspec part no. ARM1914-BLK) is built to keep a .308-class or 300 Blackout rifle flat and on target through rapid strings of fire. Made by Armaspec, this 5/8×24 threaded brake vents gas through angled ports to cut felt recoil and muzzle rise, letting a shooter reacquire the sight picture faster between shots. At 6.3 inches long, it is sized for .30-caliber and .300 Blackout platforms and is a direct swap for a factory flash hider on threaded barrels. Competitive and 3-gun shooters use brakes like this specifically to shave split times on multi-target strings.
