AR15/M4 Muzzle Brake with Crush Washer
Screws onto standard AR15/M4 ½" X 28 threaded barrels (with .223, 5.56 bore).
Muzzle Brake has two chambers with 14 ports that direct the exiting propellant gasses upwards and to both sides to reduce muzzle rise and felt recoil.
There are no open ports on the bottom of the Muzzle Brake, this will reduce the dust signature when firing prone.
