  • DETACHABLE FIREARM MAGAZINE SPRINGS FORMED FROM WIRE HAVING NON-ROUND CROSS SECTION
    Publication number: 20220155033
    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.
