Nice rifle. I need to build another of that sort of pattern...Did a Colt SP1 Carbine rebuild with a 12.7” with a pinned fake moderator to keep it non-NFA, and did not use the grenade ring on mine (can’t recall why). Really love the super simple and lightweight carbine idea.
But your wear patterning looks off to me. Too many non-worn high areas next to really worn areas. Too obvious, it would drive me crazy, which is pretty much why I avoid faking wear. (Little bit OCD sometimes!) Not sure what would make it better in my mind, but it just kind of jumps out at me after being an armorer on a variety of weapon types including AR’s, and seeing how they wear when carried and riding in racks a lot. Hopefully it is exactly how you wanted it and that is what is important!
