Doctore has a point, you can go way past 50psi with that kind of construction, why not?

Can you connect a sprinkler valve to a metal gun like this one?

Sure you can.
People generally use QEV on a full metal construction
and people whom use PVC generally use a sprinkler valve.

It's up to the builder i guess.

Anyway, on topic

The gun seems good for a spare part gun.
:P

Yes and QEV is more efficient, realasing the air faster than a sprinkler vavle ;) And if wa take right parts, we can up to 600psi or more.


It's it's the ball valve, with a spring ;)

Yes, well enought, but i'm limited by the handle, it twits when i load the spring...

Le jour de l'apocalypse zombie, i'll can fire only one time... hum after i'm dead ! :D
