A: Thanks for reaching out Brian! "5.56x45mm NATO" is the full name of the rifle cartridge your AR is chambered for. It is also known as 5.56x45mm, 5.56x45, 5.56, and 5.56 NATO; those are all different names for the same exact cartridge. And remember: if a rifle is chambered for 5.56, then it can also safely and effectively fire 223 Rem (aka 223).
