much cheaper and likely 1/2" thread, you can hook it up to the QEV with a reducer

an exhaust pipe

Eh?

Looks good - one thing though, if you want a ball valve as a reloading mechanism, it either needs to be drilled or of the three way type like this:

I suppose if i do it that way, I don't have to go about converting the metal to PVC... (FYI I was going to drill the two way ) ...and use metal for the barrel instead.

Just comes down to whatever is cheapest I suppose!

EDIT: How far would a marshmellow go operating on 80-125psi?
