Just a heads for those looking for an AR-15 that's actually in stock somewhere. I don't know which specific model(s) they have or how many they have in stock.

Good luck!
UPDATE:
It appears Vance's online is out of stock now. Atlantic Tactical is showing a couple of S&W models and RRA's in stock but this hasn't been verified by anyone:
Atlantic Tactical - Rifles
