I like this upper.

This upper is the basis of my first AR pistol build. I have a pistol brace already. I like the style of this Aero Precision upper because I find full railed hand guards to be too bulky for my tastes. I like a more minimalist approach, yet if I do need something extra to bolt on, I can.
