Abstract
Improvements in a projectile launcher with a two-part bolt is disclosed. The two-part bolt has a forward bolt that moves and locates the projectile from the magazine to the breach. The ball is maintained in the breach until pressurized air pushes the projective out of the launcher. A ball holder is biased by a spring and when the bolt is moved, the bolt will lift the ball holder and blocks loading of a second projectile. An adjustable barrel detent alters pressure on top of the projectile to create backspin. The two bolt parts forms a piston to drive the projectile forward. A spring between the forward bolt and the rear bolt to maintains an extended biased location between the two bolt components. Travel between the two bolt elements if maintained by a pin that is retained in the rear bolt with a pin keeper spring.
