    Customer service was excellent. The upper was in the mail the same day and looks like it's never been fired.

    Exactly as described, great condition, the only noticeable blemish was on the brass deflector. Shipping was quick too.

    Very good condition for a Daniel Defense police trade in, absolute steal for the price.
