Abstract

A compressed gas cartridge is provided that includes a hollow front cartridge section having a male high-pressure gas quick-connect fitting, a forward piston-receiving channel, and a projectile receptacle; a hollow cartridge rear section having a rear piston-receiving channel and a forward valve seat; a center cylinder connected between the cartridge front and rear sections and enclosing an interior gas storage space; and a piston that sealably fits within the front and rear piston-receiving channels. The piston has a solid rear portion configured with a striking surface and a hollow forward portion. The hollow forward portion has an exterior concentric seal with a rearward edge configured to sealably engage the valve seat. Piston exhaust/fill holes rearward of the concentric seal allow compressed gas to move between the gas storage space and the hollow interior of the piston forward portion during both discharge and filling.
