:D...

That's not the barrel and the chamber I'm gonna use. Ofcourse, it's going to be a bit longer for a bit more kick. In the gap, there is going to be a sprinkler valve. I've gotta get a longer hose for the blowgun to attatch. It should have a real comfortable feel.

(I know the hose will increase pilot but meeeh. The blowgun, I've modded the sh!t out of and the sprinkler valve will actuate the piston nicely)

Thanks alot mate. I really appreciate the feedback :D. I myself have always been a fan of nice compact looking guns. I'm surprised I made no primer or glue stains when connecting the tee, elbow and 2x 45's :D.

It's 1/2'' pressure pipe mate so I reckon it's about 16mm. It fits marbles very well but I'm not completely sure on the exact messurements.

Haha thanks alot for that mate. It shall be a good gun. I'm expecting a marble to piss off between 700-750fps so it will have quite a lot of power.

What are you working on at the moment?
