I'm glad you now have a functioning AR but sorry to hear what an ordeal it's been for you, Kwaynebb. A shame people like that are out there and get away with this crap. Maybe he had good intentions at first but he didn't live up to his lofty claims. You want to trust people and new businesses but it's a gamble.
If any consolation, we all have gone through things like this and the next time we do better. No doubt your next AR will go much more smoothly!
Thanks for the update and I am glad RAR did finally get you the upper, it sounded iffy for a long while!
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
