  1. james dilger

    Everything came in the shipment and the brass insert tool is a lifesaver, so easy to install

  2. Jim G

    Everything came quick and neatly packaged way easier to get these kits if you got the upper elsewhere and will probably come before your upper if you order both same day

  3. samuel

    came quick and easy to work with

    High quality parts kit for a very nicely designed lower printed receiver.
