Improvements in a more efficient use of air in a projectile launcher is disclosed. The launcher uses a two-stage air gun fire and reset to have a more efficient compressed gas usage because the gas is not wasted by performing simultaneous actions, instead, the motion dedicates a portion of the motion to firing only then transitions a “port” to close and redirect the gasses to “re-cocking” without wasted gasses going out the firing bolt. The air is redirected through a moving port or gate to allow the launcher to continue to perform and “cycle” to the point where there is low pressure in the supply tank. This prevents chopping or shredding of paintballs because the feed port of the projectiles only partially opens. The improvement allows the launcher to reliably feed and fire projectiles down to the point where it is obvious that the tank requires changing.
