Abstract

A recoil reduction system for a firearm. In some embodiments, the recoil reduction includes buffer tube housed within a buttstock, and a deformable structure for setting a clearance tolerance between the buffer tube and the buttstock to reduce lateral play while enabling smooth translation therebetween. In some embodiments, a guide pin and/or skid projections provide interference between the sliding components of the recoil reduction system when in a battery configuration, while releasing the interference during a recoil event.

First claim

What is claimed is:

1. A recoil reduction system, comprising:
a buttstock defining a longitudinal bore;
a slide member for coupling to a receiver;
a biasing element operatively coupled with said buttstock and said slide member;
a butt pad coupled to a proximal end of said buttstock; and
a buffer tube configured for insertion into said longitudinal bore along an actuation axis, said longitudinal bore being configured for a clearance fit with said buffer tube,
wherein said buttstock includes a deformable structure adapted to selectively reduce a dimension of said longitudinal bore to configure said buttstock for a close sliding fit between said longitudinal bore and said buffer tube.

2. The recoil reduction system of claim 1 , wherein said dimension is a diameter of said longitudinal bore about said actuation axis.

3. The recoil reduction system of claim 1 , wherein said deformable structure is located proximate a distal end of said buttstock.

4. The recoil reduction system of claim 3 , wherein said deformable structure includes:
a longitudinal through slot defined proximate said distal end of said buttstock, said longitudinal slot being at least partially defined by opposing lateral sides; and
a fastener arranged to draw said opposing lateral sides towards each other to reduce said dimension of said longitudinal bore.

5. The recoil reduction system of claim 1 , wherein:
said buffer tube includes a plurality of recesses formed on a lateral side thereof;
said buttstock includes structure defining a lateral through-passage for selective alignment with any one of said plurality of recesses; and
a set pin is disposed within said lateral through-passage for selective engagement with any one of said plurality of recesses for anchoring said buffer tube to said buttstock.

6. The recoil reduction system of claim 5 , comprising:
a lever pivotally mounted to said buttstock and operatively coupled with said set pin for selectively removing said set pin from said any one of said plurality of recesses.

7. The recoil reduction system of claim 6 , wherein said biasing element is coupled to said set pin for biasing said set pin to engage with said buffer tube.

8. The recoil reduction system of claim 1 , wherein said butt pad defines an open cell structure that is exposed to ambient air.

9. The recoil reduction system of claim 1 , wherein any one of said buttstock, said butt pad, and said biasing element is formed of a polymer material.

10. The recoil reduction system of claim 1 , wherein said longitudinal bore is defined by a bore wall in the buttstock, wherein the bore wall includes at least one rib that protrudes toward said actuation axis, said dimension of said longitudinal bore being referenced from said at least one rib.

11. The recoil reduction system of claim 1 , wherein said deformable structure is unitary with said buttstock.

12. A method for reducing a dimensional clearance of the recoil reduction system of claim 1 , comprising:
(a) inserting said buffer tube into said longitudinal bore of said buttstock; and
(b) adjusting said deformable structure of said buttstock to selectively adjust a dimension of said longitudinal bore and to define said close sliding fit between said buffer tube and said longitudinal bore, said close sliding fit enabling translation of said buffer tube within said longitudinal bore along said actuation axis while reducing lateral play between said buffer tube and said longitudinal bore.

13. The method of claim 12 , wherein the step of adjusting said deformable structure is performed with a fastener arranged to selectively adjust said dimension of said longitudinal bore.

14. The method of claim 12 , comprising:
providing the recoil reduction system of claim 1 in a kit,
providing a set of assembly instructions on a tangible medium, said set of assembly instructions including step (a) and step (b).
