    Love KAK components. Everything is as it should be. No defects. Reliable and reasonably priced. I use KAK upper and lower parts for all my builds.

    Great quality parts set. Came packaged in OIL for travel and installed easily on KAK upper. Great addition to finish off your upper. I only wishows it included the charging handle too!
