On ehobby asia, I just happened to stumble upon these two, and just cant decide which one...... Now I know your going to say, "This belongs in da Which gun should I get section!!!!!!!", but I have another problem. One of the reviews for the TM version says that the TM G18 is not propane/green gas ready, and has to use HF134 gas or something like that. This leads me to search up this kind of gas only to discover it must be used for all Jap GBBs (KSC!! Is this true? Help would be appreciated!
