Abstract

A folding stock assembly for a firearm includes a butt stock portion; a receiver interface portion; and a bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion.

Claims

1. A folding stock assembly for a firearm comprising:

a butt stock portion;

a receiver interface portion; and

a bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion.

2. The folding stock assembly of claim 1 wherein the butt stock portion is configured to allow for a length of pull adjustment.

3. The folding stock assembly of claim 1 wherein the butt stock portion is configured to allow for a cheek weld adjustment.

4. The folding stock assembly of claim 1 wherein the bidirectional hinge assembly includes:

a first hinge assembly;

a first latch assembly configured to releasably lock the first hinge assembly in a non-folded position;

a second hinge assembly; and

a second latch assembly configured to releasably lock the second hinge assembly in the non-folded position.

5. The folding stock assembly of claim 4 wherein the bidirectional hinge assembly further includes:

a coupler assembly configured to pivotally couple the first hinge assembly and the second hinge assembly.

6. The folding stock assembly of claim 1 further comprising:

a first catch assembly configured to releasably hold the butt stock portion in a first folded position; and

a second catch assembly configured to releasably hold the butt stock portion in a second folded position.

7. The folding stock assembly of claim 1 wherein the butt stock portion is a synthetic butt stock portion.

8. A folding stock assembly for a firearm comprising:

a synthetic butt stock portion;

a receiver interface portion; and

a bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion, wherein the bidirectional hinge assembly includes;

a first hinge assembly, and

a second hinge assembly.

9. The folding stock assembly of claim 8 wherein the bidirectional hinge assembly further includes:

a first latch assembly configured to releasably lock the first hinge assembly in a non-folded position; and

a second latch assembly configured to releasably lock the second hinge assembly in the non-folded position.

10. The folding stock assembly of claim 9 wherein the bidirectional hinge assembly further includes:

a coupler assembly configured to pivotally couple the first hinge assembly and the second hinge assembly.

11. The folding stock assembly of claim 8 wherein the butt stock portion is configured to allow for a length of pull adjustment.

12. The folding stock assembly of claim 8 wherein the butt stock portion is configured to allow for a cheek weld adjustment.

13. The folding stock assembly of claim 8 further comprising:

a first catch assembly configured to releasably hold the butt stock portion in a first folded position; and

a second catch assembly configured to releasably hold the butt stock portion in a second folded position.

14. A firearm comprising:

a barrel assembly;

a receiver assembly; and

a folding stock assembly including;

a butt stock portion,

a receiver interface portion configured to engage the receiver assembly, and

a bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion.

15. The firearm of claim 14 wherein the butt stock portion is configured to allow for a length of pull adjustment.

16. The firearm of claim 14 wherein the butt stock portion is configured to allow for a cheek weld adjustment.

17. The firearm of claim 14 wherein the bidirectional hinge assembly includes:

a first hinge assembly;

a first latch assembly configured to releasably lock the first hinge assembly in a non-folded position;

a second hinge assembly; and

a second latch assembly configured to releasably lock the second hinge assembly in the non-folded position.

18. The firearm of claim 17 wherein the bidirectional hinge assembly further includes:

a coupler assembly configured to pivotally couple the first hinge assembly and the second hinge assembly.

19. The firearm of claim 14 further comprising:

a first catch assembly configured to releasably hold the butt stock portion in a first folded position; and

a second catch assembly configured to releasably hold the butt stock portion in a second folded position.

20. The firearm of claim 14 wherein the butt stock portion is a synthetic butt stock portion.

21. The firearm of claim 14 wherein the receiver assembly is a bolt action receiver assembly.

22. The firearm of claim 14 wherein the receiver assembly is a pump action receiver assembly.

23. The firearm of claim 14 wherein the receiver assembly is a semi-automatic/fully automatic receiver assembly.
