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.

Abstract: A magazine well extension for a firearm having a magazine well in a lower receiver, the magazine well extension including a substantially hollow body including a magazine well extension portion, for covering and extending beyond an opening of the magazine well of the firearm, the magazine well extension portion being adapted and configured to guide a magazine into the magazine well of the firearm and coupling elements for coupling the body about the lower receiver of the firearm. The inner surface of the body is contoured to conform to the outer surface of the lower receiver, and the body is shaped as a grip, for use as a fore grip on the firearm.
