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 made of 4140 steel and have a black oxide finish for a long service life.
