I have the JG G36 E (the long version with the bipod) I actually ordered the C, the very short one but Airsoft World, sent me the wrong one and I couldn't be bothered to send it back (cheers ASW).... ANYWAY, it shot hot out of the box 370-390 so that was annoying as I didn't want to open it up. Perhaps a shorter barrel may not have such a high velocity?? I'm new back into the sport so am erring on the side of caution this time and getting a well recommended, entry-level RIF; G&G CM16 that shouldn't be hot.
