The magazine body joins all of the magazine's components together.  Its lateral walls have lips to prevent the cartridges from falling out and lugs that limit the upward motion of the follower.  On the front wall is the catch and on the rear wall stop lug, which together hold the magazine in the receiver.  On the bottom of the rear wall of the magazine's body is an inspection hold for determining if the magazine if fully loaded.  The walls of the magazine are ribbed for strength.  The bottom of the magazine is closed with a floor plate.   The floor plate has a hole for the lug of the stop leaf.   Inside the   magazine body are a follower and spring with stop leaf.  The follower is fastened to the upper end of the spring by an internal flange on the right wall of the follower.   The follower has a lug that ensures the staggered positioning of the cartridges in the magazine.   The stop leaf is permanently attached to the bottom end of the follower spring and holds the magazine floor plate from displacement with its lug.   Some rifles have plastic magazines that are the same in construction as the metal magazines.
