Abstract
A muzzle brake includes a muzzle brake mount, a muzzle brake cone and a muzzle brake end cap welded to form a first nozzle, a larger first expansion chamber, a second nozzle and a smaller second expansion chamber. The first and second expansion chambers have pairs of lateral windows for venting combustion gases without net lateral forces on the rifle to which the muzzle brake is attached. The muzzle brake end cap has a toroidal interior surface to recirculate combustion gases within the second expansion chamber. An alignment pin attaches to the top center of the outside of muzzle brake mount as an aid to the user to align the lateral windows in a horizontal orientation.
