Abstract
A composite ammunition magazine comprises a box with a follower slidably disposed in the box and a spring disposed between a bottom of the box and the follower and biasing the follower towards an open top. A pair of opposite lips extends from proximal ends at opposite sides of the open top in an arc to distal free ends over the open top of the box. The box and the pair of lips comprise a composite material comprising fibers in a resin matrix with the sides of the box comprising hoop fibers oriented at 0 degrees and axial fibers oriented at 90 degrees, and the pair of lips comprising lateral fibers oriented at 0 degrees and arc fibers extending in an arc and oriented at 90 degrees with respect to the lateral fibers. The pair of lips comprises more arc fibers than the axial fibers in the box.
