I've own my Mk23 for a few years now and something odd is happening to the finish of the bbl. I have attached a picture, and I'm wondering if this is something anyone has seen before.

Ugly I know, but it's normal for a newer production Mark 23. If you've had that gun for several years and the painted finish is just now flaking off you aren't shooting it enough lol.
