Abstract
A system and method are provided for a magazine-fed, pump-action firearm. The system comprises an extruded receiver having a longitudinal bore extending along the length of the extruded receiver, where the longitudinal bore forms a first opening in the extruded receiver for receiving a barrel, and a second opening in the extruded receiver for receiving a stock, a barrel extension key extending inward from an interior surface of the longitudinal bore, the barrel extension key configured to index and position the barrel, and a barrel nut configured to couple with the first opening of the extruded receiver and maintain the barrel substantially inside of the longitudinal bore between the barrel extension key and the barrel nut. The method includes extruding a receiver having a longitudinal bore, machining features on an exterior surface of the receiver, machining transverse openings in the receiver, and providing a barrel nut.
