Magazine for a Rifle Having a Fixed Magazine

Abstract

A magazine for a rifle having a fixed magazine has a cavity in an outwardly facing surface that receives a projecting boss immovable within the magazine well of the rifle. Once the magazine is inserted and the boss engages the cavity, the magazine is fixed and may not be removed from the rifle. The magazine is loaded by separating the upper receiver from the lower receiver and exposing the magazine opening, allowing it to receive rounds of ammunition.
