Abstract: The invention relates to a device for feeding cartridges (15) from magazines to small arms, in particular to rifles with a cartridge feed device (3-7, 25-29), which transports the cartridges from a tubular magazine (11) to the barrel (1) by means of a device, in particular a rocker/spoon (3, 25-29). Said device comprises a breech, which receives the cartridges from the cartridge feed device, slides them into the barrel and closes the latter. The rocker/spoon of the cartridge feed device can be removed from the intermediate chamber between the tubular magazine and the lock (13) and an interchangeable cartridge magazine (16) can be inserted in the empty intermediate chamber (21). In a first embodiment, the rocker (3) can be displaced from a front position into a rear position. In a second embodiment, the rocker (3) can be pivoted from an upper, approximately horizontal position into a lower, approximately perpendicular position.
