Abstract: A muzzle brake compensator has a mount configured to connect to the barrel in registration with the barrel axis, a body defining an interior chamber and connected to the mount, the body defining a bullet aperture registered with the barrel axis, an exhaust port apart from the bullet aperture, a nozzle element connected to the exhaust port and rotatable about a port axis, and the nozzle element defining an exhaust aperture having an exhaust feature having a characteristic angularly offset from the port axis, such that the rotational position of the nozzle element determines a direction of an exhaust force with respect to the port axis. The nozzle element may protrude laterally at an angle from the barrel axis. The nozzle element may be lateral to the bullet aperture. A pair of exhaust ports may be located on laterally opposed positions with respect to the bullet aperture.
