An improved pneumatic firing mechanism for a paintball gun of the electronic (automatic) type, having selectable burst-firing modes and integrated bolt and ram to improve efficiency and yet simplify manufacturing. The firing mechanism generally comprises a bolt formed with a forward portion and a fixed portion, and a coaxial valve piston inside the bolt, the valve piston being formed with a central passage for directing compressed gas from the gas inlet of said main body into the compressed gas storage area, said valve piston selectively preventing the release of compressed gas from the compressed gas storage area. Low pressure is employed in the gun in order to move the bolt rapidly forwardly towards its front shooting position, where the bolt causes high pressure gas to be released into the barrel through a high pressure gas passageway running through the center of the bolt. The number of paintballs fired in a single burst can be set by the user.
