Abstract

A firearm stock with a reinforcing member and related methods are disclosed. A reinforcing member has a proximal end having at least one proximal tab shaped to engage a firearm housing, and a distal end having a locking pin engagement surface and at least one distal tab shaped to engage at least one of the firearm housing or a battery tube. The member also has a longitudinal axis extending between the proximal end and the distal end, and a first wall having a longitudinal length greater than a width. The member also has at least one sidewall one of coupled to or unitary with the first wall, and at least one side tab positioned on the sidewall and extending towards a center portion of the reinforcing member.

Claims

1. A reinforcing member for a firearm stock, the reinforcing member comprising:

a proximal end having at least one proximal tab;

a distal end having a locking pin engagement surface configured to contact a locking pin of the firearm stock and at least one distal tab extending distally from the distal end;

a longitudinal axis extending between the proximal end and the distal end;

a first wall having a longitudinal length greater than a width;

at least one sidewall one of coupled to or unitary with the first wall; and

at least one side tab extending inwardly and at an angle from the at least one sidewall, and engages with and does not move relative to a ridge of the firearm stock,

wherein the at least one side tab does not contact the locking pin,

wherein the at least one distal tab extends at an angle from the at least one sidewall.

2. The reinforcing member of claim 1, wherein the locking pin engagement surface is curved.

3. The reinforcing member of claim 2, wherein the locking pin engagement surface is shaped to encircle the locking pin and allow the locking pin to pass through and engage two or more holes in a firearm receiver extension at different times.

4. The reinforcing member of claim 1, wherein:

the at least one proximal tab extends proximally from at least one of the first wall or the at least one sidewall; and

the at least one proximal tab is shaped and positioned to engage with and below a portion of a proximal wall or butt pad of the firearm stock.

5. The reinforcing member of claim 1, wherein:

the locking pin engagement surface is configured to align with two or more holes in a firearm receiver extension at different times.

6. The reinforcing member of claim 1, wherein the at least one side tab is configured to form an interference fit with the ridge of the firearm stock.

7. The reinforcing member of claim 1, wherein the at least one side tab is cut out of the at least one sidewall leaving an associated opening in the sidewall.

8. The reinforcing member of claim 1, wherein the at least one side tab has a same thickness as the at least one sidewall.

9. The reinforcing member of claim 1, wherein the at least one side tab extends at an upward angle toward the first wall.
