Abstract
Springs formed from non-round wire stock for a detachable magazine for a firearm are disclosed. A detachable magazine may have a body having a base, an ammunition follower positioned within the body, and a spring formed from wire having a non-round cross-section positioned between the body and the follower. The non-round wire provides a shorter compression height for the spring when compared to traditional round wire springs currently used in detachable firearm magazines.
Claims6
A detachable magazine for a firearm, comprising
- a body having a base;
- an ammunition follower positioned within the body;
- and
- a compression spring disposed within the body between the base and the follower and formed from a wire, the compression spring having a plurality of coils, each of the plurality of coils having a non-round coil shape and a uniform size, where the wire has a non-round cross-section and comprises a pair of substantially parallel side surfaces having a height, and a top surface and a bottom surface that are substantially parallel and have a width, where a transition between either of the pair of substantially parallel side surfaces and either of the top surface or the bottom surface comprises a surface defined by a radius, where the width is greater than the height and a ratio between the width and the height is about 2.7, and where the width is oriented generally perpendicular to an axis of compression of the compression spring.
