Best of the lower cost lr-308 uppers - Aero Precision M5 .308 Assembled Upper Receiver

I tend to stay with lower cost parts in my AR builds and have always have used various 308 uppers such as Ares Arms in the past. This is my first purchase of the Aero M5 upper and I like it so well that I have 3 more on back order with Optics Planet. Fit and finish are fantastic and I really like the forward assist screw in place of the drift pin.
