    Awesome receivers. Very tight fit. Can't go wrong with such a choice blem.

    What a deal!

    Mine arrived a lot quicker than expected with only one small scuff that bugged out perfectly with a little Flitz.

    BCM upper demo/scratched

    Great upper with a slight scratch but going to duracoat it anyways! Bought a few of these now and always satisfied!

    Already broke in!

    The BCM demo/scratched uppers are an amazing deal. Although they are heavily discounted, the imperfections in the finish are minor. Apart from a blemish and missing no logo, they are the same high quality upper, including BCM casting marks. I have bought a couple of these and in my experience, the imperfections are no more than what you would expect to see on any rifle that has spent any time outside the safe.

    Fantastic!

    Greg price, top quality- fast shipping.
    BCM rocks!
    My blem was a hardly noticeable mar on the finish. Nothing to bother with, as I’m painting it anyhow.

    Couldn't really find a blemish.

    Looks, feels, and fits like it should.

    Customer review

    I've purchased these several times in the past, and the blems have ranged from "nothing I could find" to "something I could barely find". My most recent purchase was for two of these blem uppers, and the blems were identical rub marks on the left side of each upper. I don't know if they were put there on purpose to make them blems, or maybe they are from rubbing against other uppers in a rack. One of the marks almost completely disappeared from about three seconds of rubbing with my thumb. The other mark took about 10 seconds of rubbing, and stayed a little more visible than the first, but still isn't bad. I would definitely buy again.

    Practically Brand New!

    Excellent Value! Best fit I've ever seen on a Colt M4 Lower. Shit Tight as we say in the Marines...
    Using it on a 300blackout build which is coming along nicely...

    REASER,
    TEXAS
