I work with UK, and have bought a couple of items from him over the years.
He is very matriculate with the care of his firearms. He has a tendency of underrating the condition, his 90% is everyone else 95%. If the item has a flaw he will go out of his way to point it out.
He is one of most honest people I have ever dealt with!! The only bad thing I can say about him is that he was born and raised in Kentucky, but we won't hold that against him.
