Claim:
An ammunition magazine comprising: a casing with fore and aft sides and two longer lateral 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 two tines at fore and aft positions that extend generally perpendicularly therefrom, one of the two tines having a front face that presses against the ridge to prevent forward linear and axial tilt of the follower, wherein the tines limit rotation of the follower within the casing; a floor plate coupled to the casing at the second open end; a follower spring residing between the follower and floor plate; and a stop tab, projecting internally from or near the ridge terminus 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.
