Patent attributes
A muzzle brake has body having a muzzle end and an exit end with at least one side connecting the ends. A muzzle aperture in the muzzle end is sized and configured to fit a firearm muzzle. A projectile aperture in the exit end extends to the muzzle aperture. A line segment within the space of the muzzle aperture aligns with the centerline of the firearm and defines a projectile line through the body. Apertures pass through the body with their generating lines being perpendicular to the projectile line. The apertures are shaped to allow more gases to escape in one direction and to contain gases in the opposing direction. This causes the gases to exert forces on the muzzle brake which compensates for the tendency of the muzzle to rise when the firearm is fired.
