Yes, they seem to be selling out fast just about everywhere. I bought one from Midway, had another on my wish list that I was going to get and it was available, but it was sold out a day after I put it in my wish list. The one I bought sold out two days after I bought mine.
At the last gun show this past weekend. I bought another in 300 blackout, while looking at it an older gentleman is looking at a DPMS, knowing nothing about the AR15. He was just wanting one to try out, I saw a little later that he was actually buying it. Uppers, completes, and lowers were selling like crazy. One dealer was swapping furniture around to make the sell on several to people who wanted a particular rifle with furniture that was on another.
