WE L85 HPA mag QR system

[geoffreym]

I recently got hold of a WE L85, and having previously used Gas guns, love the actual gun, but hate the gas/propane/CO2 systems which are currently available and would if at all possible modify the mags to work on a HPA system.
My idea is to have a HPA tank (with a regulator to manage the Psi) connected to the mag with a quick release system so that I can reload (albeit slowly) while not having to worry about cool down, or venting, and being able to fire full auto.

I've ordered a ra-tech adaptor system to see how the gun will work just on air (i've got a compressor which can maintain 130Psi).
any suggestions on what valves (have no problems tapping new threads on the bottom of the mags) I can use or anything else anybody can think of?

thanks
