FIELD: weaponry and ammunition supplies.
SUBSTANCE: auto-machine gun arrangement comprises a belt-fed, a cavity for cartridge in advance of a gunshot and a feeding extractor. A feeding extractor is designed as two slide-crank mechanisms, the crank arms of which are mounted on the shaft with 90° bias towards each other. Slide blocks are designed as piston shafts. The operating technique of an auto-machine gun arrangement comprises the charge of the belt, its transport, the cartridges extraction and a gunshot. The extraction is realised on the firing line and coincided with the gunshot.
EFFECT: firing speed and reliability growth, enhancement and design simplification.
