Receivers are perfectly machined. Finish is not standard milspec anodizing. It is much more like my Wilson Combat and Noveske sets. Highly recommend the for any builds. There is a major difference in quality between one of these and say, an Aero upper. Don't get me wrong, I love Aero, but this guy is on another level. Their jet black, rich anodizing is part of what makes it. High quality paired with stellar customer service makes Grey Ghost a big win for me. Will be buying more.

Love it great quality and texture. Engraved logo! Making a new ar build need to get an G17 lower from them next time.
