If you dont watch the Wilson Combat Series “Gun Guys” I recommend you check it out. Here is one of the best rundowns of the current situation and how we got here I have seen in a while. If you dont know who Hackatorn and Ayoob are, please look them up.
I’ve taken a class with Massad Ayoob - it was AMAZING!
great video. 
These are the veterans of the firearms world. I remember as a youngster seeing Mr. Ayoob in a lot of different gun magazines. The other gentleman I’m not to familiar with but I’m sure he’s a legend.
