Abstract

A pair of pistons with O-rings are mounted on a plate attach to an end of a butt of a firearm. A pair of cylinders for receiving the pistons are mounted on a plate attached to a shoulder pad and attached to the firearm by having the pistons inserted in the cylinders. An air release hole in a bottom plate of each cylinder communicates with an air outlet having an adjustable air valve to adjust the amount of damping of a recoil of the firearm.

Claims

1. A double air valve recoil damper device for shotguns and rifles, the device comprising:

a pair of pistons rigidly mounted on a butt end of a firearm spaced apart, the pair of pistons each comprising a cylindrical shaft with at least one circular groove around a perimeter of an end of the cylindrical shaft and an O-ring in the at least one circular groove;

a mating pair of cylinders mounted on a shoulder pad for the firearm, the pair of cylinders sized to receive the pair of pistons with one of the pistons in each of the cylinders fitting with an air-tight slidable fit, a bottom of each of the cylinders having an inner plate with an air release hole, the cylinders attached to the firearm by having the pistons inserted in the cylinders;

an air release outlet communicating with each of the air release holes and communicating with an adjustable air valve for adjusting and controlling the pressure required to release air from the cylinder so that a recoil of a firearm produced by firing the firearm causes the pair of pistons to be forced into the pair of cylinders to dampen the recoil and absorb an amount of shock adjustably determined by the adjustable air valve.

2. The device of claim 1 wherein the pair of pistons are attached to a plate attached to the butt of the firearm.

3. The device of claim 1 wherein the pair of cylinders is attached to a plate attached to the shoulder pad.

4. The device of claim 1 wherein the adjustable air valve is mounted adjacent to one of the cylinders at an outer end of the air release outlet and the adjustable air valve is angled outwardly away from the cylinder for ease of access.

5. The device of claim 1 wherein cylinder and piston action is parallel with gun bore.

6. The device of claim 1 wherein the pair of pistons and pair of cylinders are fabricated of light weight material so that they do not affect gun balance.

7. The device of claim 1 wherein an amount of stock length adjustment can be achieved by letting air out and using less of the stroke.
