Awsome! I am not getting where the air is stored.
Do you have a check valve. What do you use for the projectile?
Gforce1956 2 years ago
The air chamber is the short 3/4" copper pipe with the Schrader valve. The valve is used to discharge the gun if you do not wish to fire a projectile.
The barrel ID is 0.81".
It will shoot anything that will fit inside.
Marbles with cloth around it, slugs, darts, etc.
The piston valve seals the chamber to the barrel.
I have tested it up to 450 psi using the A/C compressor.
