Can a 5.56 NATO rifle shoot .223 Remington ammo?

Generally, yes. A firearm specifically chambered for 5.56 NATO can typically fire both 5.56 NATO and .223 Remington ammunition. Although the cartridges have very similar external dimensions, their chamber and pressure specifications differ. The reverse should not automatically be assumed—a firearm marked only .223 Remington should be used according to its manufacturer's ammunition specifications.
