Abstract

A magazine and methods of manufacturing the magazine are described. The magazine may comprise an elongated casing or feed tower having at least a distal end and a proximal end, and two sides longer than the distal and proximal ends, a follower having a tab extending toward one of the two sides (or proximal or distal end), and a bolt catch mechanism arranged at least partially inside and near a top of the elongated casing or feed tower, where the tab is arranged to contact and bias upward the bolt catch mechanism into a position configured to engage a bolt catch or slide stop of a firearm that the magazine is engaged with. In some embodiments, the magazine assembly may comprise a drum magazine assembly.
