1. A pneumatic actuation valve assembly comprising:
a frame having a bore axis;
a timing spool received in the frame and adapted to reciprocate along the bore axis;
a timing spring carried by the timing spool configured to bias the timing spool in a forward position at a first phase of an operating cycle;
a main spool received in the frame and configured to travel along the bore axis toward a frame forward position wherein the main spool actuates a bolt carried by the frame and configured to receive a projectile in an open position and chamber the projectile in a closed position; and,
whereas the timing spring is configured to transition rearward upon an application of a pressure at a second phase of the operating cycle thereby ejecting the projectile.
