For my M203 I've used and tested Duster Gas, HPA, Propane & Co2.
All work fine. Co2 is the best bang though.
The top half screws right into an HPA or CO2 tank.
gas mags (propane/green gas) cannot be used with CO2 or HPA. You will blow out the seals and valves. The CO2 mags use a 12g cartridge and cannot be filled with said charger. This is the same reason GBB pistol mags cannot be used with CO2 or HPA.
simply put, it is a pressure and volume issue. I've explained it before on these forums.
Nades are different since they are designed to use CO2 (depending on which one)
