Patent attributes
Disclosed is a muzzle brake for a firearm having a barrel with a muzzle and a bore extending along a longitudinal axis. The muzzle brake includes a body with an axial passageway substantially axially aligned with the bore. A high pressure chamber in the body receives combustion gases from the muzzle and includes at least one outlet port for venting a first portion of the combustion gases in the high pressure chamber. A second chamber in the body, forward of the high pressure chamber, receives at least a second portion of the combustion gases from the high pressure chamber. The second chamber has two opposing side openings in the body and includes a rear wall and a rearwardly-facing front wall upon which the second portion of the combustion gases impinge. The front wall has two rearwardly curved surfaces transverse to the axial passageway that form an apex transverse to the longitudinal axis. The muzzle brake may also include a cupped concavity in at least one of the rearwardly curved surfaces of the forward wall.
