<p>A muzzle brake (10) for a gun which comprises an annular member (12) mountable on the firing end of the muzzle (11) of the gun, which member (12) comprises a pair of concentrically located annular elements (14,15) of which the first one (14) is mounted stationary relative to the muzzle (10) of the gun and the second one (15) is slidably movable against the biasing action of a spring (19) relative to said first element (14) in a direction opposite the firing direction of the gun, said movement taking place under the influence of the exhaust gas resulting from the firing of a projectile by the gun, and said movement being from a first extreme position into which said spring (19) forces said second element (15), in which position the brake (10) is in the 'off' position, to a second extreme position where the brake (10) is in the fully 'on' position, in which position said exhaust gas can force the first element (14), and hence the muzzle (11) of the gun, to move in the firing direction, and so counteract the recoil action of the gun. <IMAGE></p> |
