Abstract
A muzzle brake for use with a gun includes a cylindrically shaped hollow body having internal threads adjacent the rear end for threadedly attaching the body to the muzzle of the gun adjacent the bore coaxially along a longitudinal axis of the barrel. The body defines an axially extending internal chamber with a flat transverse wall adjacent the forward end. Longitudinally extending, helically shaped slots are formed through the body and in communication with the internal chamber. The slots are equally distributed about the body, and each of the slots has a forward end that is angled generally toward the rear end from an inner periphery of the body to an outer periphery of the body. Each of the slots is further defined by parallel sidewalls defining an opening with an axis offset (non-intersecting) from the longitudinal axis of the barrel. The internal threads and the offset of the slots are oriented so that propellant gases escaping through the slots strike one of the sidewalls and tend to thread the muzzle brake tighter onto the barrel of the gun.
