Alexander Arms MBMMB64KIT Millennium Muzzle Brake Kit for .50 Beowulf. The Millennium compensator offers a braking effect and downward force to counter muzzle flip. It features four compound angled slots on each side directing gas backward and upward for improved efficiency and safety. This muzzle brake provides recoil and muzzle jump reduction for quicker follow-up shots. Back blast may be noticeable, but benefits outweigh this minor inconvenience.
