G&G mp5 Q's
Hi, I am looking into purchasing the G&G mp5 A4 combo from mach1 airsoft and I had a couple of questions. If I wanted to change the full stock to a folding stock, would I need anything besides just the stock? I'm not sure if the stock handguard can fit a battery in it. Also is the combo from mach1 for $310 a better or worse deal than the CAS version mp5's? Thanks for any help.
