ABSTRACT:
In an automatic weapon having a wedge-type breech 6, a linearly advancing and retracting feed finger 5 is provided to transport caseless ammunition 4 into the cartridge chamber 10a of the gun barrel 10, with the feed finger pushing against the rear face of the powder body 4a of the cartridged ammunition 4. An ammunition-receiving device is employed to prevent recoil of the ammunition 4 and consequent damage to the powder body 4a. The ammunition-receiving device includes leaf springs 2 which are disposed in the feed opening 3 of the gun housing 1, with the free ends 2a of the leaf springs 2 projecting radially inwardly to thus constrict the inner width of the feed opening 3. The free ends 2a of leaf springs 2 press on the outer surface of powder body 4a of the caseless ammunition and inhibit its forward movement.
