C Products AR-15 DuraMags Pre Marking SN Numbers?

After many hours of researching this matter and coming up with nothing I just had to make a video about it. It seems no one is even talking about any of this and it is kinds of concerning to say the least. You have to take a look at what all the firearms company's are doing and maybe you can have a clue about whats actually going on. Is is possible that C products is pre-complying with future gun control bills that have yet to pass? Is is also possible that Academy sports and outdoors is preparing for a possible 30 round mag ban? Nothing is for sure unless someone knows something I don't.
