It should. There's just two words of advice:

1) Make sure you're not using a venting regulator. These essentially include an overpressure valve in them and, placed in the pilot area like that is, could potentially trigger the valve. Needless to say, that's not safe.
2) You need to work out how you're loading the thing to make decent use of an on-board air supply.

Where can I buy me one of those awesome firering chambers :D

Seriously though, you should use a three way valve instead of a blowgun.

How many effective shot would I get out of it using a nerf bullet

one thing you could have a paintball tank attached to it and still have it regulated down lower to 30 or 40 psi, and i think some pvc will hold 200 psi.

How big is your main tank?

How big is your firering chamber?

What pressure does the regulator output?

How big is your main tank? 138 sq inches

How big is your firering chamber? 37 sq inches

What pressure does the regulator output? 15 - 25 psi

About 15 shots at 20 psi output from a 100 psi main chamberererer.

37 cubic inches sounds far too big for shooting Nerf darts though, have you tried modelling your idea in GGDT?

With a three way valve like a slide valve as a pilot, you can shoot semi-auto!

I have not yet modelled my design yet, so I don't really know what the dimensions should be. i want to be able to move the gun around easy.

Thanks for the designing website (ggdt) i have never heard it before.

Using a slide valve would work better but it would take the gun like effect out of it

Here is another design. Would it work better than the first? I would built it into wood so it looks more gun like.

Pleas give me your oppinion

I don't know if there is other type of slide valve but with the common available one with that design you will be pushing the trigger than pull it. You should move the valve near the qev to have forward direction, except you want to add more mechanical to the trigger.
