Abstract
A drum magazine for feeding cartridges to an automatic or semi-automatic firearm such as a carbine or the like. A spiral cartridge receiving channel is formed within the drum, and a magazine extension joins the drum to feed cartridges into the magazine-receiving receptacle of the firearm. A number of rotor arms extend across the cartridge receiving receptacle, and are biased to feed the cartridges there along. The rotor arms can be manually indexed backwardly, allowing cartridges to be loaded one-by-one through the open end of the magazine extension.
