Abstract
A muzzle brake for reducing gun recoil comprises a hollow cylindrical tube (7) having an open forward end and having at least two apertures in the cylinder wall (4) each which is provided with closure means (6) mounted on the tube so as to be movable between a closed position and a fully open position. Each closure means (6) has at least one associated biasing member (22) to bias it into the closed position, which is preferably preloaded to introduce an inertia into the movement of the closure means (6) which is of such a degree that the rapid blast pressure wave passes with little effect, but the longer exhaust wave effects opening. The brake further comprises at least one rearwardly directed gas deflecting surface (13, 30) to deflect the exhaust wave gases rearwards and produce a braking effect.
