There are "assault weapon" bans like that in my home state of California that ban certain cosmetic features on guns. These are completely pointless as an AR-15 is functionally no different from any other semi-automatic firearm.

Not an "Assault Weapon"
I ask because it isn't actually all that interesting as far as guns go.
It shoots a fairly low-power cartridge, roughly equivalent to 30-30, which means that it isn't powerful enough for deer hunting in some states. That's part of why it's easy to shoot even for XX folks. (Another part is the ergonomics; the stock and hand-grip make it easier to shoot correctly from the shoulder than most rifles.)
It's semi-auto, but so are most guns these days. It doesn't shoot any faster than other semi-autos. Standard capacity magazines aren't any larger.
It is possibly the most popular rifle of all time, certainly in the last 50+ years.
