.223 Remington Ammunition
.223 Remington Ammo
The .223 Remington cartridge is the American equivalent of the 5.56 NATO. Along with the NATO round, the .223 Remington is by far the most widely-used ammunition in AR-15s. It's a very powerful yet low-recoiling round, which makes it a lot of fun for recreational and competitive shooters. It has also been used extensively by the U.S. military as a lighter and easier to carry option than the .308 Winchester round.
