FIELD: weapon and ammunition.
SUBSTANCE: barrel contains a cartridge chamber and a channel where the ledges are located which form the space for passing of bullets which is smaller than the channel. The ledges are shifted with reference to each other diametrically along the channel surface. The ledges are made on the ends of equal separate longitudinal halves of the bushing with a cavity. The bushing halves superimposed along the channel axis are turned with reference to each other by 180° along the channel axis and form a cartridge chamber in the channel of barrel breeching.
EFFECT: device simplification, barrel shortening.
