Ammunition magazine

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.

What is claimed is: 
     
       1. An ammunition magazine comprising:
 a casing with fore and aft sides and two longer lateral sides longer than the fore and aft sides and first and second open ends, the casing further comprising a ridge, centrally located on an interior side of the fore side, guide rails running along insides of the longer lateral sides, the casing further comprising a stop tab projecting internally from a front of the casing constant internal curve initiating at or near the second open end and continuing through a majority of the casing of the magazine; and 
 a follower residing within the casing, said follower further comprising a follower platform with one to four tines, one of the one to four tines being at a fore position that extends generally perpendicularly from the follower platform, the guide rails contacting the follower to act as a guide for the follower, a groove serving as a detent situated in the follower platform to interface with the stop tab. 
 
     
     
       2. The ammunition magazine of  claim 1 , wherein the casing further comprises a constant internal curve initiating initiates at the second open end and continuing through a majority of the casing of the magazine. 
     
     
       3. The ammunition magazine of  claim 2 , wherein one of the one to four tines is arranged at an aft position of the follower platform that extends generally perpendicularly from the follower platform. 
     
     
       4. The ammunition magazine of  claim 2 , wherein the casing further comprises a ridge, centrally located on an interior side of the fore side, wherein a front face of one of the one to four tines presses against the ridge. 
     
     
       5. The ammunition magazine of  claim 1 , wherein the casing further comprises a ridge, centrally located on an interior side of the fore side, wherein a front face of one of the one to four tines presses against the ridge. 
     
     
       6. The ammunition magazine of  claim 1 , wherein one of the one to four tines is arranged at an aft position of the follower platform that extends generally perpendicularly from the follower platform. 
     
     
       7. The ammunition magazine of claim  1  6, wherein the casing further comprises a ridge, centrally located on an interior side of the fore side, wherein a front face of another one of the one to four tines presses against the ridge. 
     
     
       8. The ammunition magazine of  claim 1 , wherein one or more of the one to four tines is split into two regions via a vertical gap arranged at a center of the one or more tines. 
     
     
       9. An ammunition magazine comprising:
 a casing with fore and aft sides and two longer lateral sides longer than the fore and aft sides and first and second open ends, the casing further comprising a ridge, centrally located on an interior side of the fore side, the casing further comprising guide rails running along insides of the longer lateral sides, the casing further comprising a constant internal curve initiating at the second open end and continuing through a majority of the casing of the magazine, and the casing further comprising a stop tab projecting internally from a front of the casing; and 
 a follower residing within the casing, said follower further comprising a follower platform with one to four tines, one of the one to four tines being at a fore position that extends generally perpendicularly from the follower platform, another of the one or more tines being at an aft position and shaped to fit into a trough in at least a portion of the aft side, the guide rails contacting the follower to act as a guide for the follower, a groove serving as a detent situated in the follower platform to interface with the stop tab, thereby preventing the follower from eiting the magazine through the first end. 
 
     
     
       10. The ammunition magazine of  claim 9 , wherein the follower platform comprises a second tine at an aft position of the follower that extends generally perpendicularly therefrom. 
     
     
       11. The ammunition magazine of claim  10  9, wherein the casing further comprises a ridge, centrally located on an interior side of the fore side, wherein a front face of one of the one to four tines presses against the ridge. 
     
     
       12. The ammunition magazine of  claim 9 , wherein the casing further comprises a ridge, centrally located on an interior side of the fore side, wherein a front face of one of the one to four tines presses against the ridge. 
     
     
       13. The ammunition magazine of  claim 9 , wherein one or more of the one to four tines is split into two regions via a vertical gap arranged at a center of the one or more tines. 
     
     
       14. The ammunition magazine of claim 1, further comprising a stop tab projecting internally from a front of the casing.  
     
     
       15. The ammunition magazine of claim 14, further comprising a groove serving as a detent situated in the follower platform to interface with the stop tab.  
     
     
       16. The ammunition magazine of claim 9, further comprising a groove serving as a detent situated in the follower platform to interface with a stop tab, thereby preventing the follower from exiting the ammunition magazine through the first end.  
     
     
       17. The ammunition magazine of claim 9, wherein the casing further comprises a constant internal curve initiating at the second open end and continuing through a majority of the casing of the ammunition magazine.  
     
     
       18. The ammunition magazine of claim 9, wherein the casing further comprises a stop tab projecting internally from a front of the casing.
