    On a unmarked AR barrel/upper, How do you determine if it is chambered in 223 or5.56?

    Did you remove the handguards to see if it's marked? if not are there any marks?

    It's a bare barrel with absolutely no marking of any kind except a couple scratches.

    Use a chamber gauge for .223 & 5.56

    When in doubt only use 223 Rem.
