    BCM® Upper Receiver - M4 Flat Top - DEMO

    Quality that I have become to rely on from BCM. This was a Demo/Scratched receiver that I inspected and could not find a flaw in it. I am very impressed with the quality control at BCM and that is what makes them one of the best weapon makers out there.

    Blem upper

    The only upper to buy in my opinion. Fit perfectly with a BKF lower. Zero play.

    Blem uppers

    If you get the chance to get these, get them. Couldn’t find a single scratch or wear mark. Only thing is maybe the under coat was a bit light… other than that I can’t find a blemish anywhere.

    Solid

    This receiver is great, they were kind enough to throw in a note explaining the blemish but no issues here! Near perfect condition. Will get more in the future!

    BCM Blemished Upper

    I purchased this to complete a full BCM build. I was nervous being a blemished part but the reviews where great so I got one. It came quickly and I found the piece to be amazing. I couldn't find a single thing wrong with it. Looks just as good as any other upper receiver I previously purchased. Will definitely purchase again. Great work from BCM as always.

    BCM Upper Receiver M4 Demo

    I have ordered several of these Demo models and they have all looked new w/o imperfections. And, of course, as per BCM's reputation they fit tight to the barrel and lower receiver.

    Blem AR15 Upper

    If there was a blem I couldn't find it. T marked rail, heat fit extension to receiver mating. Thumbs up!

    BCM blem stripped upper

    This thing is perfect in every way looks amazing how it is considered a blem I don't know. On the other hand instillation on the barrel is ruff even with heat had to hammer in the barrel with a piece of wood and mallet even after heating the whole upper hot enough I couldn't touch it this thing is amazing the quality is top notch but if your looking for a easy barrel insulation this is not for you!
