Then what? The price of an AR will skyrocket; who’ll turn any of them in?
Nobody turns them in on this stuff. They just can’t make or sell new ones. That does mean the ‘pre-ban’ ones skyrocket, especially the magazines.
They sure won’t turn them in, in the hood, and they won’t even try to go in there and take them.
So guess who will have the guns, and who won’t have the guns?
