Also i saw the brownells made dpms compatible nickel boron bolt carrier group is on sale . Does anyone have experience with that ? Thanks

Hello, I found an Alexandria pro fab upper for a good price but cannot find much info on it. All I can find is dpms compatibile . Does anyone know if it’s a gen 1 or gen 2 style ? The only part he doesn’t have with the upper is the charging handle so I’m trying to figure out what it is so I can purchase one. Thanks
