Embodiment Construction
[0056]With reference now to the drawings, the preferred embodiment of the ammunition magazine is herein described. It should be noted that the articles “a”, “an” and “the”, as used in this specification, include plural referents unless the content clearly dictates otherwise.
[0057]With reference to FIG. 1, the magazine 1 generally comprises a body 10 having a floor end 13 and a feed end 17. The magazine 1, can have fore and aft sides and two lateral sides longer than the fore and aft sides. Feed lips 21 are provided at the feed end 17 to interface with a weapon and to guide cartridges into the firing chamber of said weapon. The floor end is capped with a floor plate 20 which is secured by a lock plate 25. A spring 35 rests against the lock plate 25, centered by walls 24 (see FIG. 6a), and floor plate 20 combination and provides tension to bias the follower 30 and the floor plate 20 so that the follower 30 will progress up the magazine body 10 as ammunition is used. Floor plate 20 sli...

Abstract
The present invention is an ammunition magazine, preferably made of a reinforced polymer, utilizing a structurally enhancing ridge, angular guide rails and a follower made to interface with said guide rails to reduce wobble. The preferred embodiment also features a protective cover that distributes forces from the spring to more structurally sound areas of the magazine, thus reducing feed end splay, and an ammunition indication system comprised of at least one window and a noticeable marker on the follower spring. The follower and magazine casing are also designed to interface to prevent the follower from popping out of the feed end and the floor plate of the magazine utilizes a locking plate and sliding relationship between the floor plate, locking plate and magazine to secure the floor plate onto the magazine casing. The cover features built in tools for, among other things, unloading and disassembling the magazine.
