    What can I say, this is one of the best rifles made for the price tag. Very reliable – not a single jam with either. Clean. Accurate. I would recommend this handgun to anyone.

  2. Falson

  3. Darryl

    I have owned a couple of rifles. As a militray person I went through many rounds and through some harsh conditions. This gun will perform every time they are called upon. As I said, CAN’T GO WRONG!

  4. Poully

    The process was user friendly and I was updated on the progress of the delivery. Very simple and fast.

  5. Johan

    Reliable, Powerful, perfectly weight and Crazy simple to clean. You could pay $800-1000 more for a “Show Piece” rifle… I guess… I really like my Ruger AR-556 5.56mm.
