Abstract
Abstract A drum-type ammunition magazine includes a plurality of concentric ammunition bays therein with each bay having disposed therein a plurality of fixed tiered partitions for supporting linkless ammunition and a rotatably mounted ammunition carrier for moving the linkless ammunition within the bays and between the fixed tiered partitions and toward a port communicating with each ammunition bay. The ammunition carriers may be operated independent of each other, enabling storage of a different type of ammunition in each of the ammunition bays.
