摘要： A gas cylinder for firearms includes a cylindrical hollow body fixed to the lower part of the barrel and loosely fixed to the tubular receiver or tubular magazine of the fire-arm. Such body is gas sealed as its bottom end with regard to the tubular magazine and has in its interior a piston which exactly fits into its inner surface and which can slide or be guided by the tubular magazine on being pushed or urged by the gasses which originate form a shot. The cylindrical body is interiorly stepped into two different diameters and the piston is loosely mounted on the tubular magazine and is prolonged, as a continuation of its adjustment area with the inner surface of the cylinder, into a coaxial tubular projections. Gas tight sealing of the cylindrical body or body of the gas cylinder is achieved with regard to the tubular magazine, by means of a joint or gland mounted on the smaller diameter part of such body which are held in place by a flexible washer or ring which fits on such coaxial projection of the piston.
