    Great upper

    Perfect upper. Bought two, both with minimal blemishes that would be there during normal use anyway unless the gun you're building is a safe queen.

    blem uppers

    hardly blemished, uppers are super tight which is awesome. Shrank my group size, needed torch to install BA barrel with nickel boron extension. Match quality, came with upper parts kit as well.

    Best damn deal I’ve seen. The upper was perfect and it looked unused. I should have bought two.

    Upper Receiver

    I purchased two of these upper receivers with blemishes. Upon arrival the blemishes were actually hard to find and when I did find them I would classify them as very minor. I am very happy with what was sent.

    BCM upper receiver DEMO?

    The upper i received was def not a demo/scratched. A bangin' deal! Even included the forward assist and dust cover parts! The only thing that I noticed is that the finish of this upper is a bit more matte/lighter colored black compared to my aero precision lower. But it doesn't matter to me because I will be cerekote-ing my receiver.
    10/10

    N/A

    The imperfection on this receiver was hard to find. The only thing that I saw was a very small scratch on the left side of the receiver. These are Well worth the purchase.

    Bcm flat top upper blem

    one of the best deals on the market. BCM products are amazing. I know it says blem, but the mark on mine simply wiped on and its barely noticeable. It operates as it should and continues to function as intended. The build is fantastic and everything fits with the kit they provide. If they go on sale again, ill def be buying more

    Blemished upper

    I bought this blem upper for my son's first father's day and his first build. I only got the blem because the regular upper was out of stock. The quality is amazing especially for a blem. The only thing I could find wrong with it was it looks like it had been dragged across a dusty counter top but it all wiped right off with just using my thumb. I wouldn't hesitate to buy another
