Linkless feed system/conveyer magazines are a high capacity "magazine" device that has a channel cut through it zig-zagging through the container. It works similar to that of a conveyer belt through channels attached to a tensioning device. Linkless feed system offers the reliability/compactness of magazines with the high volume of fire of belt feeds.
It uses an "endless chain conveyor" and a cogwheel interacts with the internal chain to advance cartridges through the channels, and the chain has multiple dummy cartridges at the end attached to push the remaining live cartridges up into the magazine's mouth along with pulling cartridges through said channels.
