I am looking for a reputable place to be a one stop shop for some custom work on my AI AE Mk III. I am wanting the rifle to be dipped or ceracoted in a camouflage patter, have my Kahles scope duracoted, and have the barrel threaded for a suppressor. I want a reputable place to ensure the threads are cut concentric to the bore, and my scope doesn't get messed up lol. I live in Indiana, but know it would probably be hard to find such a place in my state. Are there any custom shops thatsspecialize in AI's?
