I was looking to add a little personalization to a new ar build and came across USA Tactical Firearms in North Carolina. They machine their recievers in house and also do custom engraving. I'll try and get pics up tomorrow morning after work, but let me say the engraving/detail was better than I had hoped for and the price wasn't bad either. I'll be putting a Stag lpk in this week so I'll update on how easy that goes.
