Abstract

A recoil reduction stock. The device includes a shock absorber having a first end, a second end, and a spring channel extending therethrough. A coil spring is disposed within the spring channel. A spacer abuts the second end of the shock absorber, and the first end of the shock absorber contacts a rear edge of a firearm stock body. A lag stud is inserted through the spacer and the shock absorber, wherein a tip of the lag stud is configured to engage the firearm stock body, such that the spring is compressed between a rear edge of the firearm stock body and the spacer. A butt plate is affixed to the spacer, wherein the butt plate includes a hollow interior volume in which a head portion of the lag stud is disposed. The compressed shock absorber is adapted to resist expansion and absorb recoil energy when the firearm is fired.

Claims (32)

1. A recoil reduction stock, comprising:

a shock absorber comprising a first end, a second end, and a spring channel extending through the first and second ends;

a coil spring disposed within the spring channel, wherein the coil spring is configured to directly engage a main stock body of a firearm;

a spacer abutting the second end of the shock absorber;

a lag stud inserted through the spacer and the shock absorber, wherein a tip of the lag stud is configured to engage the main stock body of the firearm, such that the spring is compressed between a rear edge of the main stock body and the spacer;

a butt plate comprising a hollow interior volume in which a head of the lag stud is disposed;

wherein when the firearm is fired, the shock absorber and the coil spring compress and absorb recoil energy, and a distance between the lag stud head and the spacer is increased.

2. The recoil reduction stock of claim 1 , wherein the lag stud is inserted through a lag stud channel of the shock absorber, wherein the lag stud channel is disposed adjacent the spring channel.

3. The recoil reduction stock of claim 1 , wherein the lag stud is inserted through the spring channel of the shock absorber, such that the coil spring encircles the lag stud.

4. The recoil reduction stock of claim 1 , wherein the lag stud head comprises a lock nut secured to an elongated body of the lag stud.

5. The recoil reduction stock of claim 1 , wherein the lag stud tip comprises threading thereon.

6. The recoil reduction stock of claim 1 , wherein the spacer is composed of a material that is configured to be rigid and incompressible.

7. The recoil reduction stock of claim 1 , wherein the shock absorber is composed of a material that is configured to be compressible.

8. The recoil reduction stock of claim 1 , wherein the butt plate is composed of a material that is configured to be compressible.

9. The recoil reduction stock of claim 1 , wherein the butt plate comprises an arcuate rear edge.

10. A firearm stock, comprising:

a firearm stock body;

a recoil reduction stock affixed to the firearm stock body, the recoil reduction stock comprising:

a shock absorber comprising a first end, a second end, and a spring channel extending through the first and second ends;

a coil spring disposed within the spring channel, wherein the coil spring is configured to directly engage the firearm stock body;

a spacer abutting the second end of the shock absorber;

a lag stud inserted through the spacer and the shock absorber, wherein a tip of the lag stud engages the firearm stock body, such that the spring is compressed between a rear edge of the firearm stock body and the spacer;

a butt plate comprising a hollow interior volume in which a head of the lag stud is disposed;

wherein when a firearm connected to the firearm stock body is fired, the shock absorber and the coil spring compress and absorb recoil energy, and a distance between the lag stud head and the spacer is increased.

11. The firearm stock of claim 10 , wherein the lag stud is inserted through a lag stud channel of the shock absorber, wherein the lag stud channel is disposed adjacent the spring channel.

12. The firearm stock of claim 10 , wherein the lag stud is inserted through the spring channel of the shock absorber, such that the coil spring encircles the lag stud.

13. The firearm stock of claim 10 , wherein the lag stud head comprises a lock nut secured to an elongated body of the lag stud.

14. The firearm stock of claim 10 , wherein the lag stud tip comprises threading thereon.

15. The firearm stock of claim 10 , wherein the spacer is composed of a material that is configured to be rigid and incompressible.

16. The firearm stock of claim 10 , wherein the shock absorber is composed of a material that is configured to be compressible.

17. The firearm stock of claim 10 , wherein the butt plate is composed of a material that is configured to be compressible.

18. The firearm stock of claim 10 , wherein the butt plate comprises an arcuate rear edge.
