I am interested in getting into the GBBR scene and I am looking into the SRC AK74u. The only thing is that I want to use it for both indoor and outdoor. Off of green gas it shoots about 400fps so could I run it on duster to get something around 330fps? I hope this isn't a stupid question, I am just not very familiar with GBBs and I have no experience with GBBRs.
EDIT: I did some googling and I think I answered my question: HFC 134a wont provide enough power to cycle the weapon and it is bad for the seals. Is this true?
Kingston airsoft, we do it better.
