I got a hold of a TM MP7 that was broken. Parts are hard to find but I've found them. It basically needs the ENTIRE gear box replaced. It'll cost me just over $100. I'm wondering if anyone has some personal experience with these guns and can tell me if its worth fixing or not. I was thinking about putting a peq box on it with a LiPo battery to try and get a higher cyclic rate out of it. Or should I buy the green gas MP7? I haven't had ANY good experience with green gas guns, and the mags are so expensive!! Which is what's compelling my apprehension on buying one. Thanks in advance!
