I used Night Owl Gunsmithing exclusively. He's on the Southwest end of SLC. Sorry I don't have his number though. I threw away his card when I moved away, dang! I hope he's listed somewhere, last name I think is Fernandez or maybe first name Fernando, sorry I got CRS. There's a Sportsman's Wharehouse not too far from his place, that he occassionally bought from. Maybe they have his number if you can't find it. This guy is good, works from his home.
