.223 Or 5.56mm?

[gars320]

I have a preban Colt AR15 Match HBAR that is marked on the lower receiver as Cal. 223 but it is also marked on the Barrel as 5.56mm. The box is no help either as it is a Blue Label Model 6601 & says .223 (5.56mm). it is also marked on the BBl as a 1/7 twist. Is there a definite answer, or am I worrying about a non issue?

If it says 5.56 on the barrel that's what it is. Since .223 can be safely fired from a 5.56 chamber, it's a non-issue.

This. If it says 5.56 on the barrel, then it is 5.56, not 223. The barrel is the part with the chamber, not the lower. You can swap out lowers, but the chamber is part of the barrel. Shoot with confidence.
