Abstract

A firearm recoil absorbing device for supporting a firearm during firing includes nested inner and outer frames. The inner frame is slidably connected to the outer frame by plural rollers for relative sliding motion between the nested frames. Each frame includes two opposing sidewalls interconnected by opposing front and rear walls. A stop is mounted to the outer frame and extends into the inner frame. The stop divides the space within the inner frame into a recoil chamber and a return chamber located respectively toward the front and rear walls. One or more rods, mounted to the inner frame front wall, extends parallel to the sidewalls of each frame and slidably through the stop and the rear walls of each frame. A recoil spring surrounds the rod in the recoil chamber and a return spring surrounds the rod in the return chamber. When used to fire a rifle or shotgun having a barrel end supported by sandbags or a shooter's hand, the device includes a butt cup mounted to the inner frame for receiving and supporting the firearm shoulder stock butt. In alternative embodiments, the firearm butt cup may be self-aligning or adjustable. During firing, the recoil spring absorbs the recoil energy as the inner frame is forced from a forwardmost position to a rearward position and then returns the inner frame to the forwardmost position. The return spring counteracts the recoil spring to ease the return of the inner frame to the forwardmost position.
