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.

1. An ammunition magazine comprising: a casing with fore and aft sides and two 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;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, the one of the one to four tines having a front face that presses against the ridge to help prevent forward linear and axial tilt of the follower, wherein the one to four tines limit rotation of the follower within the casing;a follower spring residing below the follower; anda stop tab, projecting internally from or near a terminus of the ridge, and a groove serving as a detent, situated in the follower platform to interface with the stop tab, thereby preventing the follower from exiting the magazine through the first end. 2. The ammunition magazine of claim 1, 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 magazine. 3. The ammunition magazine of claim 1, wherein the follower comprises a second tine at an aft position of the follower that extends generally perpendicularly therefrom. 4. The ammunition magazine of claim 1, wherein the casing further comprises two guide rails situated opposite each other along the lateral sides of an interior of the casing, the two guide rails contacting the follower to act as a guide for the follower to inhibit rotation of the follower. 5. 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 each the one or more of the one to four tines. 6. An ammunition magazine comprising: a casing with fore and aft sides and two 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, and 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;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 therefrom, the one of the one to four tines having a front face that presses against the ridge to help prevent forward linear and axial tilt of the follower, wherein the one to four tines limit rotation of the follower within the casing;a follower spring residing below the follower; andwherein the casing further comprises two guide rails situated opposite each other along the lateral sides of an interior of the casing, the two guide rails contacting the follower to act as a guide for the follower to inhibit rotation of the follower. 7. The ammunition magazine of claim 6, further comprising a stop tab, projecting internally from or near the terminus of the ridge and generally perpendicularly from the ridge, and a groove serving as a detent, situated in the follower platform to interface with the stop tab, thereby preventing the follower from exiting the magazine through the first end. 8. The ammunition magazine of claim 6, wherein the follower comprises a second tine at an aft position of the follower that extends generally perpendicularly therefrom. 9. The ammunition magazine of claim 6, wherein one or more of the one to four tines is split into two regions via a vertical gap arranged at a center of each of the one or more of the one to four tines. 10. An ammunition magazine comprising: a casing with fore and aft sides and two 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 an insides of the two longer lateral sides;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 therefrom, the one of the one to four tines having a front face that presses against the ridge to help prevent forward linear and axial tilt of the follower, wherein the one to four tines limit rotation of the follower within the casing, the two guide rails contacting the follower to act as a guide for the follower, wherein at least one of the one to four tines is shaped to interface with the guide rails to inhibit rotation of the follower; anda follower spring residing below the follower;wherein one or more of the one to four tines is split into two regions via a vertical gap arranged at a center of each of the one or more of the one to four tines. 11. The ammunition magazine of claim 10, further comprising a stop tab, projecting internally from or near a terminus of the ridge and generally perpendicularly from the ridge, and a groove serving as a detent, situated in the follower platform to interface with the stop tab, thereby preventing the follower from exiting the magazine through the first end. 12. The ammunition magazine of claim 10, 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 magazine. 13. The ammunition magazine of claim 10, wherein the follower comprises a second tine at an aft position of the follower that extends generally perpendicularly therefrom. 14. 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 guide rails running along the insides of the longer lateral sides, the casing further comprising a stop tab arranged on a front inside face of the casing;a follower residing within the casing, said follower further comprising one to four tines, one of the one to four tines being at a fore position that extends generally perpendicularly therefrom, the guide rails contacting the follower to act as a guide for the follower;a groove serving as a detent situated in a follower platform of the follower to interface with the stop tab, thereby preventing the follower from exiting the magazine through the first open end;a follower spring residing below the follower; andwherein one or more of the one to four tines is split into two regions via a vertical gap arranged at a center of each of the one or more of the one to four tines. 15. The ammunition magazine of claim 14, wherein the guide rails interface with the follower to inhibit rotation of the follower relative to the casing. 16. The ammunition magazine of claim 14, further comprising a ridge on an interior side of the fore side of the casing. 17. The ammunition magazine of claim 14, wherein the follower comprises a second tine at an aft position of the follower that extends generally perpendicularly therefrom.
