  • Patent number: 5305677
    Abstract: The Invention is a muzzle brake-bullet stabilizer, cylindrical in form affixed to the end of a rifle or pistol having internally a primary exhaust stage, a transition stage and nozzle. The primary exhaust stage being adjacent to the muzzle and consisting of a limited number of exhaust port holes drilled radially into progressively smaller internal bores serving as the primary exhaust stage and muzzle brake. A metering orifice being a strait cylindrical bore section of a diameter slightly larger than that of the bullet. The nozzle being conical with the small diameter being that of the metering orifice and increasing slightly thereafter, serving to increase the velocity of the remaining exhaust gases in a manner as to stabilize the bullet in its transition to supersonic velocity of the outside air from that of a negative velocity with respect to the exhaust gases.
