Abstract

An improved buttstock for a firearm is disclosed, the buttstock comprising a comb, the comb comprising an indexing surface on a comb extension, the comb extension being configured to move between an expanded configuration and a retracted configuration; a buttstock, the buttstock comprising a buttpad extension indexing surface, the buttstock being configured to move between an expanded configuration and a retracted configuration. A common lock can secure both the comb extension and the buttpad extension in a fixed position. The common lock can release one or both of the comb extension and the buttpad extension to slide with respect to the body of the stock.

Claims

1. An adjustable stock for a firearm comprising:

a comb extension configured to move between an expanded configuration and a retracted configuration, the comb extension comprising a comb extension indexer positioned on a surface in a lower portion of the comb extension;

a buttpad extension configured to move between an expanded configuration and a retracted configuration including a buttpad extension indexer on a surface in a forward portion of the buttpad extension;

at least one stationary indexer tab in a fixed position relative to the firearm, the at least one stationary indexer tab having a first surface configured to engage the comb extension indexer and an opposed second surface configured to engage the buttpad extension indexer; and

a single common lock for securing the at least one stationary indexer tab to each of the comb extension indexer and the buttpad extension indexer.

2. The adjustable stock of claim 1, wherein the single common lock passes through a hole or slot in each of the at least one stationary indexer tab, the buttpad extension indexer and the comb extension indexer.

3. The adjustable stock of claim 1, wherein the single common lock has an open position and a closed position and when in the closed position resists movement of both the comb extension and the buttpad extension.

4. The adjustable stock of claim 1, wherein each of the buttpad extension indexer and the comb extension indexer include alternating teeth defining grooves in the indexer.

5. The adjustable stock of claim 1, wherein the single common lock comprises a cam lever.

6. The adjustable stock of claim 5, wherein the at least one stationary indexer tab is a first stationary indexer tab, the first stationary indexer tab is configured with a first surface and a second opposed surface and the first surface defines a series of teeth having a first orientation and the second surface defines a second series of teeth, the second series of teeth having a second orientation that is about 90°

to the first orientation.

7. The adjustable stock of claim 6, comprising a second stationary indexer tab, the second stationary indexer tab in a fixed position relative to the firearm, the second stationary indexer tab having a first surface configured to engage the comb extension indexer and an opposed second surface configured to engage the buttpad extension indexer.

8. The adjustable stock of claim 7, wherein the first stationary indexer tab and the second stationary indexer tab are a unitary part.

9. The adjustable stock of claim 8, wherein the first stationary indexer tab and the second stationary indexer tab are biased outwardly to provide a force against the buttpad extension indexer when the buttpad extension indexer is mated with the stationary indexer tabs.

10. The adjustable stock of claim 9, comprising two comb extension indexers, the two comb extension indexers configured to apply a compressive force to a pair of stationary indexer tabs when the comb is mated with the buttstock.

11. The adjustable stock of claim 10, wherein each indexer comprises at least one surface that defines a set of teeth in a planar arrangement.

12. The adjustable stock of claim 11, wherein the set of teeth are horizontally arranged.

13. The adjustable stock of claim 11, wherein the set of teeth are vertically arranged.

14. A method, comprising:

utilizing the adjustable stock for a firearm of claim 1;

loosening the single common lock;

adjusting a comb height;

adjusting a length of pull; and

tightening the single common lock to fix the comb and length of pull at new locations.

15. The method for adjusting a stock of claim 14, further comprising expanding and retracting a buttpad extension to adjust the length of pull.

16. The method for adjusting a stock of claim 15, further comprising expanding and retracting a comb extension to adjust the comb height.

17. The method for adjusting a stock of claim 14, further comprising adjusting the comb height without adjusting the length of pull.

18. The method for adjusting a stock of claim 14, comprising adjusting the length of pull without adjusting the comb height.

19. The method for adjusting a stock of claim 14, wherein the comb extension and a buttpad extension are clamped around a stationary indexer comprising a series of vertical teeth on a first surface and a series of horizontal teeth on a second surface.
