Opening a trigger valve allows the gas in the control reservoir to escape through an exhaust port, resulting in the gas valve being rapidly...
1. A quick-release valve air gun for shooting a projectile, comprising: a barrel with a muzzle end and a breech end;a primary gas reservoir of a gas valve configured with a primary gas outlet in gaseous communication with the breech end of the barrel;a piston receptacle mounted within the primary gas reservoir so as to be surrounded by the primary gas reservoir;a piston with an inner end configured to slide into the piston receptacle and with an outer end that provides the gas valve with an airtight seal in a closed state, wherein a control reservoir hav...
