Cerakote over the blemished anodizing whatever color you want
Mine had a spot in the magwell and a tiny spot by the safety selector. no big deal, I did more blemishing putting the roll pin in the bolt catch. My $1300 brownings come with small finishing flaws occasionally too. I dont get worked up about it since its going to get marked up behind the seat of the pickup anyways.
But Im sure sure the next batch of anodizing will be corrected.
