It's a billet upper that has the barrel nut machined in to the reciever. It comes with the barrel nut wrench. It only takes aero precision enhanced rails.

I know that, but they are not pictured. So i just wanted to make sure they are still coming with the upper receiver. the box doesnt even match the upper either. Just want to make sure.
