Abstract: A compensator is described, having a primary venting system that directs high pressure gas in a downward direction, thereby creating a dynamic or resistive force as the gas bears on the bottom surface of the compensator housing before being redirected at upward angles. This primary systems works to push the compensator down thereby negating muzzle flip. A secondary venting system, which consists of one (or more) cylindrical gas expansion chamber(s) forward of the downward vent, works in combination with the primary system by allowing residual lower pressure gases to expand and disrupt within the expansion chamber(s) before being vented in an upward direction. This secondary system creates a passive action in that the gas is not directed to bear on any particular surface, but is allowed to expand and bear on all available surfaces before venting upwards thereby creating an additional downward force further reducing muzzle flip.
