A recoil reducing device for a firearm including a hollow sleeve received within a chamber of the stock of the firearm, with one end directed toward the receiver of the firearm and the other end directed away from it and with closures at opposite ends of the sleeve. A pair of radially projecting lugs externally position the device and space the sleeve within the chamber. A weighted piston is slideably received within the sleeve and biased into a central position therein by springs on opposite ends. The piston is provided with a lubricant reservoir and means for permitting the lubricant to flow from the reservoir to the outer surface of the piston. Further, the closure at the sleeve end directed toward the stock is provided with an outer face presenting closely spaced teeth at equal angular intervals for establishing a predetermined angular orientation of the device within the chamber. The opposite end closure has an outer end face presenting a tool receiving recess for permitting adjustment of the angular orientation.
In combination with a firearm having components including a barrel, a receiver, and stock integrated into fixed relationship so that no relative movement between said firearm components may occur when firing, a recoil reducing mechanism disposed within said stock, said mechanism comprising housing means forming a sleeve having one end directed toward said receiver and an opposite end directed away from said receiver, closures at the opposite ends of said sleeve, a pair of radially projecting lugs externally of said sleeve at the opposite ends thereof and on opposite sides thereof, a piston slideably received within said sleeve for slideable movement therein upon recoil of said firearm when firing, and resilient means for biasing said piston into a central position between the opposite ends of said sleeve, a reservoir within said piston for containing a quantity of lubricant, and means for supplying said lubricant from said reservoir to an outer surface of said piston for providing lubricant between said piston and sleeve.
