I now have the Barrel, Dies, and primed cases from Midway, now just have to decide if I'm going to pull the barrel from the upper i have or purchase another upper that i have some ideas on.

Go with another upper.....easier to swap uppers as needed. You can get them fairly cheap, fact is, I think Midway has them on sale right now for what it's worth.
