    5.56 barrel engraving

    Posted by Unknown on 31st Mar 2021

    Purchased a new 5.56 mill spec chrome lined barrel. So far so good on the barrel, but I really do not like the new engraving. It is under the handguard and hard to identify without removal. I shoot multiple calibers through my AR, and would like it marked traditionally on the muzzle end.
