This is making the rounds today. Word is a guy brought this M2 into a gunsmith who then very stupidly, took it apart, took photos and in a an inspired bit of cosmic idiocy, posted it all over his social media. He then turned the owner in to the feds. Boot lickers gonna boot lick I suppose. Some seem to be positive it was a ATF sting. Either way, old boy’s business facebook page is not down the memory hole from the response he got. Probably came as a shock to him how unsympathetic his customer base was to his actions.
