They're the exact same thing, dumbass..223 is the NATO round, you fucking moron.You have been implying it. The fact is that a .223 NATO round is one of the least deadly rifle cartridges.
Is there a .223 NATO round, dope?
Actually, 5.56 is the NATO round used in the M-16. .223 is the round used in the civilian version, the AR-15
No, actually they are not. Pressure is the primary difference between the .223 and the 5.56. The .223s are loaded to lower pressures and velocities compared to 5.56. Due to its lower pressure, you can safely fire .223. ammunition in a 5.56 chambered gun; however, the same cannot be said in reverse. It is not safe to fire 5.56 ammunition in a .223 chambered gun.
Yep.
Of course nearly all weapons of this type are actually chambered for 5.56
AR-15's are.
