Abstract
A cartridge feed mechanism for automatic firearms comprising an endless chain for feeding cartridges of different ammunition types which chain can be selectively driven in both directions is characterized in that a feeder device is provided which is or can be coupled with two magazine arrangements and which, due to its particular design, can alternatively feed cartridges from the one or the other magazine into the chain, depending on the direction of movement of the chain, and that the feeder device is so designed that every time the direction of movement of the chain is changed the cartridges already present in the chain are fed back while at the same time cartridges from the other magazine arrangement are fed into the chain.
