Improvements in the guns of compressed gases of two guns, characterized in that in the cylinder head there is a quality that allows to house the bottle of compressed gas that is being used and another spare bottle arranged parallel and juxtaposed to the first one. The reserve gas bottle has a screw cap, while the one being used has a threaded neck adapted to the internal thread of a cap integral with the head of the gas bottle receiving cavity. The neck of the gas bottle incorporates the displaceable stem valve, which opens when the bottle is attached to the sleeve. From the bottom of the cap adapting the bottle part a conduit that has the derivations that carry the gas to the expansion cylinders, which have the communication valves with the upper and lower guns to be able to drive the studs of the cartridges to proceed to the shooting.
