Claims

1. A buttstock for a firearm comprising:

a buttstock frame having a forward end and an opposing rear end, said buttstock including a frame wall and one of a series of openings and a series of projections extending along said frame wall between said forward and rear ends; and

,

a buttstock accessory supported on said buttstock frame, said buttstock accessory including an accessory wall and the other of said series of openings and said series of projections extending alone said accessory wall;

said series of openings and said series of projections being adapted to interengage one another and at least partially secure said buttstock accessory on said buttstock frame.

2. A buttstock according to claim 1, wherein said frame wall has an interior surface at least partially forming a frame passage extending between said forward end and said rear end.

3. A buttstock according to claim 2, wherein said frame passage includes a groove extending along at least a portion of said frame passage.

4. A buttstock according to claim 2, wherein said buttstock frame includes a mounting rail between said forward end and said rear end.

5. A buttstock according to claim 4, wherein said buttstock accessory includes a mounting flange positioned adjacent said mounting rail.

6. A buttstock according to claim 5 further comprising a fastener securing said mounting flange along said mounting rail.

7. A buttstock according to claim 1, wherein said accessory wall has an interior surface and an exterior surface, said interior surface at least partially forming an accessory passage with an open end.

8. A buttstock according to claim 7 further comprising a cap secured on said buttstock accessory along said open end of said accessory passage.

17. A buttstock according to claim 1, wherein said series of openings are evenly spaced-apart at a first interval distance, and said series of projections are evenly space-apart at a second interval distance.

18. A buttstock according to claim 17, wherein said first interval distance and said second interval distance are substantially equal.

19. A buttstock according to claim 17, wherein at least one of said first interval distance and said second interval distance is about ½

of an inch.

20. A buttstock according to claim 1, wherein said series of openings is disposed along said frame wall, and at least an opening of said series of openings extends through said frame wall into a passage extending along said buttstock frame.

21. A buttstock according to claim 20, wherein said passage includes a groove extending along at least a portion thereof, and an opening of said series of openings extends through said frame wall and into said passage along said groove.

22. A buttstock according to claim 20, wherein said opening is substantially rectangular.

23. A buttstock according to claim 4, wherein at least one of said frame passage and said mounting rail extends substantially entirely between said forward end and said rear end.

24. A buttstock according to claim 1 further comprising a buttplate supported on said buttstock frame at said rear end.

25. A buttstock according to claim 24, wherein said buttplate is integrally formed on said buttstock frame.

26. A buttstock according to claim 1, wherein said buttstock frame includes one of a second series of openings and a second series of projections extending along said frame wall.

27. A buttstock according to claim 26 further comprising a second buttstock accessory supported on said buttstock frame, said second buttstock accessory including a second accessory wall and including the other of said second series of openings and said second series of projections.

9. A buttstock for use on an associate firearm having an associated receiver extension, said buttstock comprising:

a buttstock frame having a frame wall with an interior surface, an exterior surface, and a first series of uniformly-spaced mounting features disposed along said frame wall, said interior surface at least partially forming a frame passage for accepting the associated receiver extension; and

,

a buttstock accessory supported on said buttstock frame in proximal relation to said exterior surface, said buttstock accessory including a corresponding second series of uniformly-spaced mounting features adapted to interengage said first series of mounting features and at least partially secure said buttstock accessory on said buttstock frame.

10. A buttstock according to claim 9 further comprising a retaining member securing said buttstock frame on the associated receiver extension.

11. A buttstock according to claim 10, wherein said retaining member is an end member engaging said buttstock frame adjacent said frame passage.

12. A buttstock according to claim 10, wherein said buttstock frame includes a retaining passage extending generally transverse said frame passage and said retaining member is a retaining pin extending through said retaining passage and engaging the associated receiver extension.

13. A buttstock according to claim 12, wherein said retaining pin is retractably supported on said buttstock frame.

28. A buttstock according to claim 9, wherein one of said first series of uniformly-spaced mounting features and said second series of uniformly-spaced mounting features includes an opening, and the other of said first series of uniformly-spaced mounting features and said second series of mounting features includes a projection.

14. A buttstock kit for installation on an associated firearm having an associated receiver extension, said kit comprising:

a buttstock frame having a frame wall with an interior surface, an exterior surface, and a plurality of evenly-spaced openings extending into said frame wall, said interior surface at least partially defining a frame passage adapted to accept the associated receiver extension;

a buttstock accessory including an accessory wall and a plurality of evenly-spaced projections extending from said accessory wall, said plurality of projections being cooperable with said plurality of openings and adapted to at least partially support said buttstock accessory on said buttstock frame along said exterior surface thereof; and

,

a retaining member adapted to secure said buttstock frame on the associated receiver extension.

15. A buttstock kit according to claim 14, wherein said accessory wall includes an interior surface and an exterior surface, said interior surface at least partially forming an accessory passage.

16. A buttstock kit according to claim 15 further comprising a cap securable on said buttstock accessory along said accessory passage.
