A magazine for a firearm with a magazine well and a reciprocating bolt. A body of the magazine is engaged within the well and has a top, interconnected front, sides and rear walls, and a bottom defining a cartridge holding interior. A spring supported within the interior contacts the bottom and upwardly biases a follower positioned atop the spring toward an opening in the top, through which the cartridges are loaded into the magazine. A feed tower integrated into the top supports a pair of feed lips positioned along opposed edges defining the opening. An aperture is formed in the top rearward of the feed tower. A rear upward projection of the follower aligns with the aperture and, following discharge of a final cartridge, elevates above the top in order to actuate a separate bolt catch or bolt hold open adaptor to prevent a forward returning motion of the bolt.
