A pneumatic gun firing ram for firing one or more paintballs. The paintball gun includes a body defining a bore, with the bore being in communication with a valve for selectively releasing compressed gas to fire a paintball. A piston is located within the bore, and a rod is mounted within the piston for sliding movement. A hammer is mounted on an end of the rod opposite the piston, the hammer being movable between a first position and a second position relative the piston. A clamp substantially surrounds the rod at a region adjacent the hammer, and a pneumatic valve is adapted to move the pneumatic ram from a first position in the bore at a distance from the poppet valve to a second position in the bore proximate the poppet valve. The clamp is adapted to hold the pneumatic ram in the first position until sufficient pressure has built up to cause the pneumatic ram to overcome the clamp, causing the pneumatic ram to strike the poppet valve, thereby releasing the pressurized gas stream and driving the projectile from the gun.
