These are some of the basics about Guns or Gun operations that anyone should know before they should form an opinion on how to address a "gun problem".
There are many people who claim the AR-15 bullets (the .223) are uniquely deadly, or that you can get shot one place and have it exit somewhere else, and other myths propagate by FakeNews outlets like The Atlantic or NYT.Some of these rumors were created by the military to make the troops more comfortable with using a gun that was far less powerful than the AK-47's they our troops were facing, and much weaker than the hunting rifles they had used at home. But sometimes weaker is better. Wounded soldiers cost more resources than dead ones, and lighter guns/rounds are easier to carry and shoot: and that's why the military chose it. But the facts are that.223 isn't even the most powerful varmint round, and is one of the weakest of the rifle rounds. It is so weak that it can't be used to hunt deer or larger game in many states. Anyone trying to sell this AR-15 bullets are more deadly than other rifle bullets, is either a fool or a propagandist. And if they're a media organization with a single fact-checker, you know which one.
Assault Weapon", to include civilian semi-automatic weapons (one squeeze of the trigger fires one bullet), because it had a few cosmetic features in common with assault rifles, and because the public might not be able to understand the difference. The media and AP immediately went along with the ruse to dupe the public. So an assault weapon is just a low-powered (smaller cartridge) hunting rifle with some wooden parts replaced by plastic parts (to lighten it), and some cosmetic accessories thrown in; like a pistol grip, barrel shroud, flash hider, accessory rails, or collapsable/foldable stock. Most guns have removable magazines, and the biggest difference coastal progressives point to is a pistol grip or magazine size. But all these features are easily swappable after-the-fact, none of which changes the lethality at all, and people can convert most rifles back and forth in about 10 minutes. Which is why gun enthusiasts think gun controllers (and their voters) are completely uninformed about guns
