Pneumag On a Classic Valve

[robnix]

I'm thinking about trying a pneumag mod on a classic valved mag. I have the pneumatic parts, needed. I'm not worried about walkability, just a light, short, trigger pull and a nifty unique mod.

Will this work with an RT/pro on/off in the valve or will it need a ULT?
Will it chuff with the ULT?
Am I wasting my time?

it will work with the rt on/off mine did.
