Abstract:
A muzzle brake in combination with a gun comprising:an annular member mountable on a firing end of the muzzle of the gun, wherein the annular member comprises a pair of elements,the first element is mounted stationary relative to the muzzle of the gun, andthe second element is slidably movable against biasing action of a means relative to said first element in a direction opposite a firing direction of the gun,said movement taking place under the influence of exhaust gas resulting from the firing of a projectile by the gun, said movement being from a first extreme position into which said biasing means forces said second element, in which position the brake is in the `off` position, to a second extreme position where the brake is in the fully `on` position, in which position said exhaust gas can force the first element and the muzzle of the gun to move in the firing direction to counteract recoil action of the gun.
