(33,982 posts)For one, .223 Remington is not 5.56 NATO.
M855 is 5.56×45mm NATO. You can fire .223 Remington in a AR, but you cannot fire M855 in a bolt Remington .223. Why? Pressures are different. M855 is a cartridge for war, not game. .223 Remington is a non-war ancestor of the 5.56 NATO.
Or to put another way, .223 Remington is rated up to 55,000 psi, 5.56 NATO all the way up to 62,366 psi.
I mostly agree with Erza's estimate, but I'd lean toward the high end. For comparison, the 7.62x54R is notoriously brutal to fire. Like, you go to the range all day with it, you go immediately to your chiropractor afterwards. Most people will fire it once or twice, and then they're pretty much done with it. Humorous comparisons of the 5.56-firing AR, 7.62x39mm AK47, and the 7.62x54R Mosin-Nagant below:

Bottom line, the AR-15/M16 is a tack driver. Insanely accurate at much longer distances than the sloppier competitor, the AK-47. However, an AR Pistol is:
1. Shorter, so you have less leverage to hang on to it. (No foregrip allowed, by law.)
2. No stock, so you can't brace it against your shoulder.
3. Lighter, so it soaks up less recoil/transfers more recoil to your hands.
4. Doesn't develop anywhere near the muzzle velocity of a full-length barrel, so you're going to blind yourself with the fireball/not punch through armor like a rifle can.
