Anyone who has fired a short barrel rifle with a muzzle break or even a standard flash hider knows how uncomfortable it is for the shooter and everyone nearby. Our muzzle device re directs the sound and blast away from the shooter and folks nearby. This is one piece design made from 6061 T-6 aluminum then hard anodized. Since the opening at the muzzle is .375” in diameter, no gasses are trapped so no erosion occurs. Available in ½-28 and ½-36 thread size. Supplied with crush washer.
