    BCM-solid and super-fast shipping, as always!

    BCM parts simply work, even the ones they label as "blem". Rock solid components for rifles you have to rely on.

    Always a great value.

    I have used these blem uppers for almost all my rifles/pistols and most have had no signs of why the are blems. Only one was an obvious blem, but still a great value.

    Blem upper

    As usual I couldn’t be happier.
    I purchased 2 BCM blemished uppers.
    Although the upper receivers had minor scratches (As posted).
    Cosmetic blems Don’t bother me a bit. Thank you for offering these to us Instead of throwing them in a bin for recycling.
    I beat the crap out of my rifles So minor scratches prior to the build is irrelevant Plus I normally hate my rifles with rattle cans.
    I am a Huge fan of all BCM products
    And I am in love your MCMR rail.
    I have the 15” MCMR rail on an 18”.DMR
    Super lightweight. And super durable.
    These 2 uppers will both have the MCMR rail.
    I trust my life to BCM products.
    BCM rocks!

    Blem uppers

    Always super fast shipping and even though they are blem parts I can’t ever find anything wrong, not even scratches, quality control at its best, and I’m a sucker for free stickers when I get gun parts and there’s always a few in there, love it, even got a free BCM beanie with last purchase which is why I like buying BCM, makes me feel like a valued customer

    Blem upper

    These uppers are great. Finished multiple builds with these uppers not only do you have a hard time finding the “blem” (all of mine have looked better than new), but very little squaring required when compared to their brands. Paired with AR Performance barrel and get Clover leaf groups at 100yds. Don’t waste money on another upper!

    Worth Every Penny

    Bought 2 stripped uppers, worth every penny. They were blemished but I couldn’t find the blemish on it. Will definitely buy some again.

    What blemish?

    Bought one of these only thing that look blemished was the dust cover itself. the upper itself I noticed nothing wrong with it.

    Blem upper

    I bought the blem model so I knew what I was signing up for just so people know the blems are very noticeable other than that product is great

    Blem uppers

    These are now my go to upper for builds. I have yet to find any significant flaws. Some the barrels can be very tight fitting, but I haven't had any other trouble with these upper receivers
