Since the motivation for buying an AR or an AK seems to be an issue here, I would like to comment on the reason most people who I know who bought one of these weapons did so. First, a lot of people over the years have had an interest in those weapons but never felt the urge to buy one UNTIL the government started to talk about imposing restrictions on them. Then those people figured if they had any interest in having one they had better get it quick and the guns started flying off the shelves. This first started in the 1990s and has happened periodically since. In other words, not nearly so many weapons would have been sold if the gov had kept it's mouth shut.

Second, the guns are easy to shoot well and they are fun to shoot. That is a huge reason they are so popular, they're fun.

Third, the ammunition isn't that expensive. More expensive than .22 but not so nearly so bad as most center fire calibers.

Fourth, ARs are extremely versatile weapons. You can set them up to do anything from prairie dog hunting to long range target shooting to home defense.

Fifth, regardless of what the big city progressive types think, ARs and AKs give a person much more confidence that they can effectively defend themselves than Mr. Biden's double barrel. And they also give any potential criminal that much more pause.

Finally, throughout our history civilians have had free access to the same kind of rifle that the military has had, and in fact during times of technical transition they have had access to much better weapons than the military was equipped with. There is nothing unique here.
