So i purchased a second hand Khaos the other day. I loaded new batteries into it, and it wouldn't work. After spending an hour, and a half or so taking it apart and putting it back together I finally realized that it wouldn't work because the top part of the magazine was missing. Everything else is fine with it, and after spending the time i have on it i'd rather get it working than return it, is there anyway to replace the part i'm missing?
Tl;dr The top part of the magazine is missing, and I'd like an idea on how to replace it.
