“I have ordered two of these receivers now. The first order was to replace a polymer upper - I have come to despise polymer as the heart of my weapon. From now on only quality forged aluminum for me. Obviously, the quality of the Aero was a cut above my original. In fact I liked it so much I purchased another for a future 300 build. The anodizing was uniformed with excellent "T" markings on the rail. Nice snug fit for my lower and zero issues. Aero is an excellent company in my experience and the price is unbeatable with Arm or Ally.”
“Excellent machining. Not sure if the receiver or my pins Also Aero Precision) were out of spec but they were hard to work at first. They will eventually break in though.”
