Great price and both items installed perfectly. In addition, unlike other kits, the c-clip was installed on the door pin. If you’ve ever tried to chase down one of these c-clips, you know this is a huge bonus!

Got a couple of these upper parts kits to finish a couple uppers that I have. I’m very pleased with the quality and the price of them. Also a nice touch that the tiny “C” clip is already installed on the rod. The finish on the covers appears to be a little thin in a couple places but in no way affects the performance. Buy with confidence.

The ejection port cover didn’t fit on 2 different uppers for some reason. (One Aero and one no-name) It did fit fine on an Anderson upper I had laying around though, so it will still get used. Everything else worked just fine!

The roll pin was material was too thick and would not compress when tapped in with starter punch. I had to replace roll pin with another brand. Dust cover did not want to latch close initially. It took some working, but finally opens and closes just fine.
