ABSTRACT:
The magazine includes a clip magazine (22) above a drum magazine (11) and connectable to an automatic weapon. Door (15) is hinged at its lower edge to open downwardly from clip magazine (22). The torsion spring (21) can be wound by external crank (20), and the spring bias can be relieved by pushing latch plunger (60). The protrusion (102, 103) of the last round follower (85) moves progressively along the spiral path (81) of the drum magazine (11) and its three links (86, 88 and 89) move through the turn and into the clip magazine (22) to push the last round of ammunition to the weapon.
