ABSTRACT:
A muzzle brake having improved recoil, stabilization and blast control is comprised of a one-piece housing member securable to the muzzle end of a gun barrel and cone-shaped closure member with a relatively long outlet passage. A spent gas bulk head formed integrally with the tubular housing member is positioned a short distance from the barrel muzzle and has a bullet passage therein which is 50 percent longer than prior art passages for better stabilization. Spent gas vents in the first and second chambers causes significantly more spent gases to be vented to the atmosphere before the bullet leaves the muzzle brake and, at the same time, provides better stabilization, concussion and blast control. Spent gas vents in the first chamber are on the top side and angulated away from the muzzle to control the direction of the muzzle blast and concussion away from the shooter and avoid kicking up dirt or sand when shooting from a prone position. The long first and second bullet passages in the bulk head and in the closure member have slightly larger internal bore diameters relative to the bullet so as to allow for more misalignment tolerance of the muzzle brake with existing threads on a barrel. Slots opening to the atmosphere on the larger second chamber are transverse to the longitudinal axis of the brake which permits larger openings for venting spent gas and also provides better control of gun muzzle.
