Abstract
A gas powered weapon including a housing for holding a pressurized gas cartridge and a projectile. A hammer mechanism is utilized to drive the cartridge into a stationary firing pin to cause the discharge of the cartridge thus providing a pulse of pressurized gas to shoot a projectile outwardly. A gas seal is disposed adjacent the firing pin to prevent back pressure behind the cartridge, whereby maximum gas pressure is available to shoot the projectile. The gas seal is located away from the non-firing position of the cartridge, such that the gas seal does not impede the motion of the cartridge when the device is fired.
