I JUST had a convo w/ my FFL about the PTR. He states this is as close as most of us will EVER come to the real deal. He said the tooling for the PTR was actually purchased from HK and it's a very high quality rifle. No doubt the Spike middy is awesome, but I think the PTR is unique and still fits the criteria for a super sweet, hard-to-find "black rifle" or however you want to label it. And a straight up trade? I'd do it!
