"of all the people I shoot with (~100 odd Trap, Skeet , Sporting Clays, Practical Pistol, Three Gun, Pistol Silhouette, NRA Service Pistol, NRA Service Rifle, Deer Hunting Buddies) there is one AR owned."
How many of your ~100 friends shoot three gun or NRA Service Rifle? ARs are the dominant rifle for both types of competition. Every 3 gun competition I have been to, 90% of the competitors are using ARs. It may be not as much with NRA Service rifle, but definitely >50% use ARs in Service Rifle. Although many people have multiple ARs, there are a significant number of shooters who have only one. Mostly the new guys.
According to Stag arms, they have been putting out about 30,000 ARs a year for the past ~2 years, and they are a new entrant in the AR manufacturing community. That is a lot of ARs.
How many ARs can the average American afford? I don't think that most of these ARs are going to current owners, but new ones. In each of my past three visits to a gun store in the past month, I have seen at least one first time buyer picking up an AR.
I have only 1 AR myself, and I am saving up for another. The number may not be 50% but it is pretty darn close.
.1-1 % is a gross underestimation.
