    BCM Quality at a Discount

    If you are looking for a great deal on a quality upper and can live with a little blemish, look no further. I have purchased a couple of these uppers and couldn't be happier. Great, price and rock solid quality.

    My new upper

    Super excited to get this. Never know what you’ll get for a blem, but I got a good one! Best price out there for sure. Thanks for the stickers and free upper parts kid. One hell of a deal.

    Blemished???

    BCM Upper Receiver - M4 Flat Top (M4 Feedramps) Complete (Unassembled) - DEMO/Scratched - As Advertised my “blemished” upper had a minor scratch on the rail and was sold at a discount. I was amazed when I received it as I had to look hard to find the “blemish”. This is a testament to your high standards. As my build will be a working gun and not a safe queen this minor issue will not be a factor. Thanks and look forward to continuing using BCM for future builds.

    BCM4 Stripped Upper

    Awesome product. I bought 2. Couldn't find a blemish on one and found what I think to be the blemish on the other. It's so small I may have done it just opening it and it disappeared once I oiled it up.

    Upper blem

    This is by far the best upper receiver I’ve ever had. I got it with the expectation of having a little something wrong because of the blem, but when I got it there was absolutely nothing wrong with it. No scratches or anything. Even for a blem receiver the qc was phenomenal.

    Best deal out there

    Tight fitting, high quality upper. Perfect for a project that’s going to be painted or one that looks are secondary to function.

    Yep - its scratched...

    but still a great value for the money any day. And I'm probably putting another mark or two on it soon enough anyway. Thanks BCM!

    Great Deal, no noticeable blemishes

    Received the upper and can’t find anything wrong other than the forging mark is not very legible. Can’t go wrong with this upper for your next build!

    Stripped Upper

    Received the blem upper and the “scratch” on the side wiped right off. Will be building it on a Noveske gen 1 lower. Fit tight and everything seems to be machined just right. No BCM mark except right above the gas port.
