Rook Muzzle Brake for 5.56 (1/2 x 28TPI)

The ROOK muzzle brake’s unique design allows for 60% less recoil than a traditional A2 birdcage.  The innovative asymmetric side ports allow expanding gas to work against recoil.   The upper ports reduce muzzle flip and by being located off-center, do not obscure the shooters line of sight. No ports on the bottom of the ROOK brake reduces dust when shooting prone.  The ROOK is available in both ½” by 28 and ⅝” by 24.  Both are made of 4140 steel and have a black oxide finish for a long service life.
