Yeah, your piston's too short!

DR your link does not work.
Are you going to fill the chamber through the back near the blowgun or directly into the chamber. If you are filling through the blowgun, you won't need the spring there. Otherwise it looks good.

If you could imagine your valve doing that, it should be fine. Asides from the length it all seems ok. Be cautious with threads, as they will leak.

Uh...no they wont?
As long as you tighten them enough with the help of a lubricant such as teflon tape, they should be fine and leak free.
@tape fist,
As long as you find a spring that can keep the piston sealed against the barrel while you fill the chamber with air, it should be fine. Assuming you're filling from the chamber and not the pilot.
