    The rifle is well made, nice and clean. Feels good in the hand. I have not been able to shoot it as I'm waiting on ammo.

    Even though there was a mix up on the upper being sent in the wrong color I'm still going with 5 stars due to the excellent customer. The shipping left something to be desired because the USPS actually lost my kit. With help from Shooters Gate it was found in Dallas and then finally sent to me in Oklahoma. The kit appears to be well made with everything you need. Im looking forward to getting the correct upper so I can build my rifle.
