The M4SD-II muzzle brake provides high efficiency recoil reduction and two durable, sacrificial baffles for use inside M4SD-II sound suppressors. A focusing cone reduces flash commonly associated with brakes and tuned ports in the primary baffle chamber provide vertical muzzle rise compensation. CNC Machined and outside diameter ground from high strength, corrosion and wear resistant, 17-4 precipitation hardened stainless steel, the M4SD II muzzle brake is black oxide finished.
1/2×28 threads offer compatibility with most 5.56mm Ar-15/M-4 carbine family weapons. The M4SD II muzzle brake is National Tactical Officers Association (NTOA) approved, and is optimal for precision weapon systems where minimal disturbance of the optical sight picture during the firing sequence, accurate calls, and rapid follow-up shots are ideal.
