Like I said, all your "facts" are but statistical noise. Here are some real facts for you:
Americans own about 30 million semi-automatics--about 15% of all guns. Semi-autos are used for the same purposes as other firearms: target shooting, hunting, and protection. AR-15s, M1As, and M1s are the most popular center-fire target rifles in America, easily outnumbering all other rifles in the annual National Rifle and Pistol Championships.

Now let's take that apart and see what it might mean with regards to AKs. If those three particular models "easily outnumber" all the others, then they represent at least 50% of the semi-auto rifles. That in turns means that no model in all the "other rifles" can be more than (50% / 3) / 2 = approx. 8% of that number. We have to divide by 3 because there are 3 "most popular", and then by at least 2 to have it "less popular". So that makes 2.4 million at most. Even if take your "companies", they will hardly keep more than half that number for future sales, so that makes 3.6 million. It is only 7% of 50 million, the latter being a very conservative estimate of the number of AKs worldwide.
