Can't wait to get mine either... most likely going to be another pistol build. Impact Guns had them in stock for a little while, but they wanted $320. This is the best price I've seen on them in a while.
Picked mine up today from the FFL. It actually arrived two days ago, just couldn't get away from work early enough to pick it up. Joe Bob's shipped very quickly (ordered on Thurs, arrived on Mon) and I had the transfer done at Pawn Express in Lagrange.
The Pawn Express folks were super nice and great to deal with. They charge $20 to transfer, but they have a special going. If you like them on Facebook they waive their transfer fee. They also had PMC 55gr XTac for $9.95/box if you mention their Facebook deal... had to pick a few of those up as well.
