just one final question, if a GBB is classified as HFC134a ready, can you use either regular propane(with the AI adapter), Airsoft 'green gas', and HFC134a gas in the same gun, if they are technically the same.

huh?
HFC134a-------------\
Crappy Tire Propane---|-------- all the same with different names??
AS Green gas---------/
