    Exactly as expected

    The stripped upper came exactly as described. The forward assist and dust cover + hardware are in a sealed plastic bag included in the packaging. My blem upper had a couple of small marks (wouldn't even call them scratches) on the flattop which looked like there was an optic mount placed then removed...not a big deal at all. There's a package insert to remind you that the barrel extension will be a tight fit, just use a heat gun and you're good to go. Definitely worth it to me to get a quality BCM part and save a few bucks on something I'm going to spraypaint anyway.

    Upper Reciever Demo

    Everywhere this upper is sold out. Decided to try this Demo one. This is the best barrel to upper fit going. Very tight needed to heat upper with heat gun and than tap barrel in to upper. Advertised as Demo/ Scratched but it actually looks new. Great price. Thanks.

    great for the price, but no logo

    amazing upper for the price, so called DEMO/ scratched will be covered be optic. only real grip is how tight the port door is to close, but that will break in and is not necessarily a bad thing for a rough use gun. I'm defiantly buying another

    BCM Upper Receiver - M4 Flat Top/Demo/Blemished

    The Fit and finish on the BCM upper is as expected. Had to heat up the upper receiver in order to install the barrel. Once the barrel was installed, the enhanced feed ramps on the barrel lined up with the feed ramps on the receiver. Great product, I would definitely purchase this again. The only blemish the upper receiver had was small nick on the coating.

    Bcm upper

    I have to say I am very impressed with the repeatable quality of bcm, I will continue to do business with them for my next builds. The blemish upper had only 1 tiny scratch on the coating on the very end of the threads.

    BCM M4 Flat Top Upper Receiver with cosmetic blemi

    The blemished upper I received has a good solid fit on the barrel extension and did require some warming up with a heat gun. I looked over this unit before assembly and was not able to determine there were any cosmetic defects and if so it would be a moot point after a few matches.
    I definitely will by these blemished receivers again for future builds or retrofits.
