Right now i run the gun at 180psi. too bad, i want to go much more higher like 400 to 600psi but my air condition compressor is giving me problems but i'll fix it or i'll get another one.

Ammo i'm using right now is AA batteries and round lead balls i cast myself. as for the T in the pilot area i'm still debating if i'll keep it or remove it because by removing it means more work for one shot meaning, to fire the gun i'm gonna thread the schrader valve onto the handle, pressurize the gun, close the ball valve unthread again then fire the gun. so maybe yes maybe no.

I'll post a video soon. by the way thanks for comments.

It doesn't, that's why I never built it ;)
