7075-T6 Forged Aluminum Upper Receiver, Type III Hard Coat Black Anodized Finish
Includes Forward Assist & Dust Cover (INSTALLED)
I bought 6 of these and I like them very much, especially for the price. They all had excellent finishes, no milk marks and provided a tight finish. The one thing they could do to improve it woul be to mill both sides of the picitiny rail just above the charge handle are like Aero. I will buy more.
