a hammer moveable within the hammer chamber from a ready-to-fire position to a firing position adjacent the discharge valve, the hammer including an aperture having a diameter greater than the first diameter of the hammer conduit for receiving at least a portion of the hammer conduit within the aperture in at least the ready-to-fire position, wherein the hammer is biased to a ready-to-fire position by a hammer return spring.
8. The compressed gas gun of claim 7 , wherein the hammer return spring is positioned in the hammer chamber forward of the hammer.
9. The compressed gas gun of claim 7 , further comprising an exhaust valve in communication with the hammer conduit for venting compressed gas.
10. The compressed gas gun of claim 7 , further comprising a solenoid valve adapted to selectively control a supply of the compressed gas to the hammer conduit.
11. The compressed gas gun of claim 10 , wherein the solenoid valve is operated by a trigger.
12. The compressed gas gun of claim 7 , further comprising an electronic control circuit for controlling a firing operation of the compressed gas gun.
13. A compressed gas gun, comprising:
a gun body;
a breech in an upper portion of the gun body;
a bolt moveable within the breech from a loading position to a firing position, the bolt having a bolt aperture therethrough;
a pneumatic assembly in a lower portion of the gun body, the pneumatic assembly including a high pressure chamber for receiving compressed gas from a compressed gas source, a hammer chamber, and a discharge valve between the high pressure chamber and the hammer chamber, wherein the hammer chamber comprises:
a hammer conduit disposed within the hammer chamber, at least a portion of the hammer conduit having a first diameter; and,
a hammer moveable within the hammer chamber from a ready-to-fire position to a firing position adjacent the discharge valve, the hammer including an aperture having a diameter greater than the first diameter of the hammer conduit for receiving at least a portion of the hammer conduit within the aperture in at least the ready-to-fire position, wherein the hammer is biased to a ready-to-fire position by a hammer return spring;
a solenoid valve in communication with the compressed gas source and adapted to selectively direct compressed gas to the hammer conduit;
a trigger frame connected to the gun body including a trigger in communication with the solenoid valve for initiating a firing operation of the compressed gas gun.
14. The compressed gas gun of claim 13 , further comprising an electronic control circuit for controlling a firing operation of the compressed gas gun.
15. A compressed gas gun body, comprising:
a breech in an upper portion of the gun body;
a pneumatic assembly in a lower portion of the gun body, the pneumatic assembly including a high pressure chamber for receiving compressed gas from a compressed gas source, a hammer chamber, and a discharge valve between the hammer chamber, wherein the hammer chamber comprises:
a hammer conduit disposed within the hammer chamber, at least a portion of the hammer conduit having a first diameter; and,
a hammer moveable within the hammer chamber from a ready-to-fire position adjacent the hammer conduit to a firing position adjacent the discharge valve, the hammer including an aperture having a diameter greater than the first diameter of the hammer conduit for receiving at least a portion of the hammer conduit within the aperture, wherein the hammer is biased to a ready-to-fire position by a hammer return spring.
16. The gun body of claim 15 , wherein the hammer return spring is positioned in the hammer chamber forward of the hammer.
17. The gun body of claim 15 , further comprising a bolt moveable within the breech from a loading to a firing position, the bolt having a bolt aperture therethrough.
18. The gun body of claim 15 , further comprising a conduit in communication with the hammer conduit extending from a lower portion of the gun body.
19. A method of firing a compressed gas gun, comprising:
providing a pneumatic assembly disposed in a gun body, the pneumatic assembly including a high pressure chamber for receiving compressed gas from a compressed gas source, a hammer chamber, and a discharge valve between the hammer chamber and the high pressure chamber;
providing a hammer conduit disposed within the hammer chamber, at least a portion of the hammer conduit having a first diameter;
providing a hammer moveable within the hammer chamber from a ready-to-fire position to a firing position adjacent the discharge valve, the hammer including an aperture having a diameter greater than the first diameter of the hammer conduit for receiving at least a portion of the hammer conduit within the aperture in at least the ready-to-fire position, wherein the hammer is biased to a ready-to-fire position by a hammer return spring;
