Excellent Assembled Upper
This is a well machined and finished assembled upper. You really can't go wrong with Aero Precision. And Aerospace Arms has been great to deal with. This is the second upper I've bought from them and both times they shipped out fast and had excellent prices. The barrel extension fit pretty snug but not overly tight.
