UPDATE: I called and asked if he still had the Spikes build AR on the counter for sale. Of course he did (no one is paying that much for a spikes lower and a model 1 upper). I told him that I had been in a few days prior and that I recognized the gun as one I had traded in to him over the summer. He said "That is one of our shop builds" with a hint of annoyance. I told him that the serial numbers and parts matched my build that I traded in. He started to backtrack and said "Oh well, uh, my wife marked these and said it was a shop build." He seemed sincerely embarrassed. He said that the new tag would be changed. I didnt mention price because I couldnt care any less how much he sells it for.
I am going to stop by this afternoon or tomorrow to see if it has been changed. He never recognizes me so being "outed" isnt a concern for me, not that I would care anyways.
That is pretty bogus.
