Where does a 19 year-old high school dropout get that kind of disposable income? I'm assuming a cost of about $400-500 per rifle, and AR's cost a hell of a lot more than that. And then, he would have had to fill out a Firearms Transaction Record Form 4473 for each one, without raising any red flags?
I didn't keep track, but I would not be surprised if twice that many might move through me in any given year, second hand, and w/o paperwork.
Why is such a number significant? What is it supposed to indicate?
