    Packing care given to what I exspected to be a blem was well above my exspectations.
    Mounted in short order to my PSA pc built lower cleanly with no tools. Pin gap not measurable. All marks disappeared with a wipe of a lightly oiled cloth.
    As a 22 + yr Vet and Homeland Security Plank Owner. I thank your Team for thier survive to our Country and the care given to my Upper.

    Back from the range, very very happy with my upper from CBC. People stoped shooting to watch if I would ever miss the 6” foo paddle at 200 yards. Shot on the swing and missed 1 out of 10
