Abstract

The present invention is a self-leveling follower for an ammunition magazine. Side extensions provide greater stability to the follower and aid in its self-leveling feature. The follower according to the present invention is also manufactured to facilitate removal from and insertion into the magazine casing when maintaining the magazine. Additional features provide greater utility by improving bolt-stop capacity and consistency of ammunition feed.
