A barrel-moving device for guns which comprises a pneumatic counter-recoil cylinder having a hydraulically operated barrel-moving cylinder. A driver connects operatively the counter-recoil cylinder with a gun barrel. The barrel-moving cylinder is in communication with the counter-recoil cylinder hydraulically and pneumatically and a hydraulic connection conduit is disposed between the barrel-moving cylinder and the counter-recoil cylinder. Finally, a manually operated pump is effective selectively in two feeding directions and is disposed in the connection conduit.
