Are you worried that a 5.56x45 might explode in it since it mentioned .223? I wouldn't worry about it. The commies over at Russian American Armory Company use .223 and 5.56x45 interchangeably.
I thought that was so, however I wanted to confirm with others that are more knowledgeable than me. I'm not fond of the ar system and the ak format suffices. Thanks!
I thought that you can shoot .223 out of a 5.56 barrel fine, but you really don't want to shoot 5.56 out of a .223 barrel... I could be wrong but that is my understanding.
But was your barrel chambered for .223 or 5.56? I believe the 5.56 is slightly larger bore than the .223. Hence shooting 5.56 through a .223 barrel its a tight fit.
