The idea is that you have two disks and in between a pilto valve like a solenoid or something. Maybe even a blowgun? The first disk is stronger than...

Last post

when the high pressure air hits the valve, there is a chance that the valve will jump open.

If I used a solenoid valve with a CO2 regulator would the Co2 keep coming out the barrel or would I get multiple shots? Need replys
