The SI Defense Muzzle Brake features a unique design that greatly reduces felt recoil when compared to the standard A2 Flash Hider and helps shooters stay on target. The reduction in muzzle rise leads to even more controllability, which makes this muzzle brake great for burst and auto capable firearms. Not a flash hider.
Installation Instructions: Recommended torque is 15-20 ft-lbs, the use of a crush washer is also recommended. Material: steel, and manganese phosphated per mil-spec.
