Abstract

The barrel of an automatic shotgun is provided with a downwardly depending cylindrical element which enclosed a portion of the cylindrical magazine. A sleeve-like element is slidably mounted on the magazine within the cylindrical element and an annular gas chamber is defined between the sleeve-like element and the cylindrical element. At least one communication aperture is formed between the barrel and the annular chamber and gas seals are provided between the sleeve-like element and the cylindrical element on opposite sides of the annular chamber. The recoil mass is slidably mounted on the cylindrical magazine adjacent the sleeve-like member so that the gases entering the annular chamber will drive the sleeve-shaped element against the recoil mass to actuate the mechanisms of the gun.
