Yeah, I'm replying to a 4 month-old comment. I have the same issue, brand new AIM NiB BCG, ran +/- 100 rounds and had all sorts of flaking around the cam pin when I cleaned it. Also some unsightly staining all along the carrier, some of which are my own fingerprints, that I can't get off.

Sep 09, 2020 · The Brownells M16 5.56 Bolt Carrier Group TiN MP might be the most affordable titanium nitride coated bolt carrier group on the market. It packs a lot of performance into a surprisingly affordable package.
I have a TiN coated bolt and carrier for one of my AR's. It shows almost no wear after thousands of rounds. Standard parkerized carriers will show some wear on the underside where the hammer rides on it and on the flats where it rides in the upper but the Ti coating doesnt show any shiney sport or color changes.
