My VFC metal body has a slight wobble near the back of the receiver between the upper and lower half. Does anyone know any good remedies? I've read that for real steel, people buy rubber wedges to jam in there, but I worry that it won't fit on our AEGs because the gearbox gets in the way and the shape won't fit. I also am concerned that even if I dremel out the wedge to fit on top of the gearbox, it might interfere with the charging handle spring when you pull that back?
