You connect a Quick disconnect, which looks like this

onto a male quick disconnect and ball valve... Which you can see in this picture.

You cannot see the fill valve on my finished gun, due to bad picture quality and the angle of the fill valve...

This valve had quite a bad day today... I don't know if it's even fixable... Maybe with a lathe or something :x Good thing I have a lathe and CNC to use :wink:

Trying the first shot at 80 psi today... While it was -12°F (about 24.4°C) out... My piston basically ripped the valve in half... I have no bumper or padding, so the piston came back very, very fast, slamming and sticking into the 2" male, and ripping the 2" female in half... The pilot valve and piston flew off in a way that hit me in the stomach and flew another 3 feet...

At least the target was decimated exactly where I was aiming :shock:

I shot a 1" ball bearing through a Dell computer case 8)
