    As expected.

    Condition as described, slightly marred finish.

    Otherwise an excellent upper, can only ding it for the barrel mounting surface being slightly less than true, almost unnoticeable and easily solved with a very minor amount of lapping. Would say it is closer to true than average, though.

    Is slightly tighter than normal, but this was desired and expected for a solid fit once heated slightly before fitting barrel.

    BCM Upper Demo/scratched

    The Upper came if it was blemished I could not-find where. Good job. Purchased a complete lower the next day at local gun shop.

    Great as per usual

    The stripped upper came in and there were no blems that i could find. The upper is not marked BCM which i didnt remember seeing in the description but i may have just misread it.

    Very nice quality

    I plan on buying more. Barrel fit is tight, but that is why you are buying this upper in the first place. Keep building them men ;-)

    Perfect upper

    Only had a small scratch that could only be seen when holding it at a certain angle. Barrel fit tight and needed to be heated to fight into the upper. That let me know the fit would be snug and accuracy wouldnt be an issue. I love BCM

    Really impressed

    I really can't find a scratch or ding on it , assembly was easy everything fit well including the barrel extension fit snugly really can't be beat for the price, the finish matches up perfectly with my bcm kmr alpha rail also I couldn't be more pleased with this receiver.
