A paint ball gun is connected through a first gas pressure regulator to a supply of pressurised gas for maintaining a high gas pressure in a first chamber in the gun and a second gas pressure regulator is connected between the first chamber and a second chamber in the gun to maintain a working gas pressure in the second chamber greater than atmospheric pressure but less than the gas pressure in the first chamber. A pneumatic control valve is arranged to receive gas under pressure from the second chamber and direct it selectively to a pneumatic ram mounted for sliding movement in a cylinder in the gun between a retracted position and a forward position in which it opens a valve to admit high pressure gas from the first chamber to the barrel to fire a paint ball. An electrical switch for the control valve is connected to an electronic control circuit which incorporates a micro-switch operated by the trigger of the gun.

[ What is claimed is:] [1.] A paint ball gun comprising:a first pressurised gas circuit for delivering pressurised propellant gas from a supply to a barrel of the gun for propelling paint balls therefrom, the first pressurised gas circuit including a valve;a second pressurised gas circuit connected to the gas supply to receive gas therefrom, the second pressurised gas circuit comprising a pneumatic ram, and a pneumatic valve for driving the pneumatic ram in sliding movement in the gun between a retracted position and a forward position in which it strikes the valve in the first pressurised gas circuit to open it and a clamp for holding the pneumatic ram in the retracted position until sufficient gas pressure has built up for the pneumatic ram to overcome the clamp;an electric circuit adapted to operate the pneumatic valve; anda trigger connected to the electric circuit to operate it.
