I ran across a thread wherein the OP was selling AT-Xs in 6.5 PRC. I would love to have one of these so I PM'd the OP and received no reply. It was a special run, I get it. To complicate matters, I want a left-hand variant. So, do lefty AT-Xs exist, and, if so, who should I get to do the metal work? I can buy the barrel from Mile High, but the bolt will still need to be opened up.
