You can buy QEV's from 3/4" all the way down to 8-32 threads, and possibly smaller. What is the diameter of the bore of your rifle?

SPEC:
-1/2 cooper pipe(as cannon)
-QEV
-quick change adapter as tank it is so that is uses cO2 canisters
-1/2 blowgun
- and the rest needed to put it together(nipples and other crap)

will this one work??

If you want a 1/2" copper barrel, no. That valve won't provide enough flow. I suggest you brows the wiki for more information regarding valves and how to size them. For the record, people tend to get angry at new members for asking simple questions, or for not searching/researching first.

The specs say 140 psi but you could probably take it too 500 psi or so without failure. Still, CO<sub>2</sub> vapour pressure is 800-1000 psi, what exactly are you planning to fill it with?
