So you can't trust the barrel markings?

According to ATK you can't
ATK, the parent company of ammunition manufacturers Federal Cartridge Company and Speer, published a bulletin entitled “The Difference Between 223 Rem and 5.56 Military Cartridges.” In this bulletin, ATK stated using 5.56 ammo in a .223 rifle could result in “…primer pocket gas leaks, blown cartridge case heads, and gun functioning issues.”
However, ATK dropped this bomb in the bulletin on the .223/5.56:

“It is our understanding that commercially available AR15’s and M16’s – although some are stamped 5.56 Rem on the receiver – are manufactured with .223 chambers.”

There are criminals among us who are both homicidal and incorrigible. Their parents took a shot at civilizing them and failed. Their school teachers took a shot at them and failed. The odds are overwhelming that government welfare programs and penal institutions took a shot at them and failed. If it ever becomes your turn to take a shot at them, don’t fail.

Sounds like that would be a lawsuit waiting to happen for any company that mismarked their barrels.
