ABSTRACT:
A recoil reducer for guns, particularly shoulder-fired guns, comprises a sealed elongated cylinder partially filled with a heavy liquid such as mercury and divided into at least two chambers by partition structure formed with a restricted orifice through it so as to retard forward movement of the mercury from the rear to the forward chamber when the gun recoils, the reducer preferably being mounted in the gun with its rear end lower than its forward end so that the rear chamber is normally full of liquid and the forward chamber is only partially filled, the heavy liquid due to its inertia reacting against the forward wall of the cylinder and the rear surface of the partition in opposition to the rearward movement of the gun during recoil, combining with the retarded flow of liquid through the orifice connecting the rear chamber to the forward chamber, to absorb much of the energy of recoil.
