I initially tried to buy an AAC SBR upper, but fortunately I could never had find an AAC in stock and bought an Aero Precision instead. Not only dd I save $300-$400, the Quailty of my Aero Precision is perfect. I just received my stamp and the upper ran perfectly with both supersonic and subsonic ammo. Highly recommended!
