Just made a little xrv valve. pretty good for its size.

(ammo is rolled electrical tape against cardboard at 40 psi with a small air chamber)

It could be made very clean with the spring and hammer running coaxial (around) the barrel in a similar manner to an airforce condor.

This kind of thing would certainly have potential with shock pump pressures.

Very nice drum beat at the start of the vid :D
i like it alot i tried to make one of these myself but could never find the right parts.
i reckon you should stick a cap gun hammer on it and make a semi auto piloted piston gun.
