This was my project before. I tried to modify it, but I don't have time now, so it is in a semi-finished state. It is a metal body, PTS stock. The internal gearbox is assembled by G&G original parts, and the motor is also G&G. But its hop-up is incomplete, and the inner barrel is also short. So it is sold cheap. It is a very good choice for parts or advanced players to practice modifying AEG.
