## Abstract

A stock for a small arms weapon that includes a first member that includes a distal end which has a receiver extension connection structure, a proximal end, a first longitudinal axis extending between the proximal end and the distal end, and a first cross-sectional profile perpendicular to the first longitudinal axis which defines a maximum outer dimension of the stock. The stock further includes a second member connected to the first member which includes a third end adjacent to the proximal end, a fourth end spaced from the distal end, and a second longitudinal axis extending between the third end and the fourth end such that the first longitudinal axis and the second longitudinal axis are disposed at an acute angle. The stock further includes a chamber inside the second member that is sized and configured to house a power supply for a small arms accessory.

## Claims

### Claim 1

A stock for a small arms weapon comprising:
an upper frame member for receiving a receiver extension which comprises
