Wonderful topic!
Mine
1. Level 10 bolt stem loose and not sealing
2. Missing rail bushing
Not mine (Assuming "your Mag" was a generalization)
1. Back end of sear not able to properly engage on/off pin. It was hitting the brass on/off bottom. This involved non-AGD parts, so alignment/fitment was the root cause. Slightly modifying the on/off bottom was the workaround fix.
2. MM2K9 velocity issue. I've been pestering Luke to disclose his fix since he offered it (and subsequently discontinued it). My suggested, although not practical, fix was a slightly longer bolt, but this was based on data provided by others and some assumptions. One person was able to machine a longer, Level 7 (I assume) style bolt, and provided feedback that it worked. Thinking about it more now, perhaps a longer bolt stem would have done the same thing. I have never actually had an MM2K9 body in my possession.
