Abstract

A muzzle brake with reduced blast overpressure may include a body having a top, a bottom, and an attachment hub. Vanes may extend from the top to the bottom. A first vane may be located at a front of the bore in the attachment hub. The first vane may have a forward-angled internal surface. A second vane may be located axially forward of the first vane. The second vane may have a forward-angled rear surface and a forward-angled front surface. A third vane may be located axially forward of the second vane. The third vane may have a rearward-angled rear surface. The forward-angled internal surface of the first vane may include an inner surface adjacent the bore and an outer surface adjacent the inner surface. The inner and outer surfaces may be angled differently with respect to the longitudinal axis.
