Just worked on my first VFC AEG. Just a couple hours ago actually, installed tb barrel and Raptor FET. I was quite impressed with the gun overall. As ghost mentioned, piston was clear polycarbonate. He says replace, but you can get a few seasons out of a good polycarb piston with up to M120 spring. I was impressed at the tolerances. The gearbox went together as smoothly as any Marui I have ever worked on. Other Chinese gb's need tricks to hold pieces in place due to slackness in tolerances.
