    Bcm blem upper

    Ordered 2. One looks pristine and one has a slight mark near the top. Quality parts for a quality price. Will definitely be buying these when they become available again

    Blemished? Somewhere?

    Just buy it. Don't worry about the classification that its blemished. This is a great example of the BCM standards for quality control - I can't find the blem. Your mileage may vary, but I'll take another opportunity to buy this part.

    Blemished m4 upper

    Fantastic quality, as expected of BCM. The “blemished” upper is superb- I cannot identify an actual blemish on this piece, save for a light mark/scratch that bugged out with a cloth. Finish is excellent, just waiting on a barrel to come in before I can comment on fit.

    BCM® Upper Receiver - M4 Flat Top (M4 Feedramps) Complete (Unassembled)

    No Brainer

    Being a bit OCD, I was worried about buying a blem/demo part for my new upper build. I must say, this was absolutely the best deal I've ever had on a rifle part! I inspected this thoroughly and could only find one very tiny and faint scratch that I can only assume is the "blem". I could have easily just made that while handling it myself though. You save some additional money by doing the easy assembly yourself (comes with all the parts). Definitely worth the chance for half off a product that I know will be amazing quality. This will be my go to for future builds as well.

    Great upper for a build

    Being a dent/demo upper, I was expecting at least a few scratches, etc. but there was only a barely noticeable blemish. I used this upper in conjunction with an Aero Lower and a SOLGW SS 16” .223 Wylde Bbl, along with BCM Furniture. I have been getting sub moa results. The receiver provides an extremely tight fit for the barrel used. I set my wife’s blower dryer on high for about 12 minutes to heat up the upper enough and had to use an oven mitt to connect the two. The lower receiver also mated well to the upper and though the lower has one of these tension screws, it is wholly unnecessary. There is hardly any slack between the upper and lower receiver. Great product. Keeping my eyes open for when they will be in stock again for a pistol build.
