so i tried to fire my gun at 25 psi, and it wouldnt fire. is there a minimum pressure that it takes to fire a coaxial piston gun?


if you guys couldn't tell by my username, and all of my questions, this is my first time building a pneumatic gun, and i do not know too much about the whole piston dealey.

thanks

perhaps if your piston was too heavy?
try it at higher pressure, i usually start testing at 60 - 80 psi

Well if its not working at low pressure maybe the air is just leaking throught the equilization hole so try the higher pressure and go from there.

Turn the gun barrel down so the piston is against the barrel, then hold it there and pressurize it.

there is, it depends on the spring behind the piston, the pressure must more than the spring
