I am using the semi design for a airsoft gun

But instead of having the tee connecting the qev and blowgun im going to have the blowgun connected directly and doing the semi auto mod.

I will then run it off 12grm co2 cartrages from this

Manufacturer information here

And there lies my first problem... How do i connect that to the blowgun input? Please help!
Anyway... Here are the parts i was talking about
3: 1/4 to 1/4 BSP Elbows - 1 for the qev to blowgun. 1 for the chamber and one for the air supply
1: Blow gun - Obvious - Has 1/4 BSP fittings
1: 1/4 QEV
1: 1/4 Cap (For the chamber)
Thanks for looking all, looking forward to answers.
EDIT: Oh and what sort of fitting would i need to connect the output of the qev to a 6mm I/D tube?
