    Upper blemished receiver, great deal, nothing more than a pencil mark as a blemish. Fit is very precise use of mild heat, to install barrel. Out of the people I know who have bought upper receivers including a colt I have. Hands down BCM is without a

    Highly recommended

    BCM blemished upper

    Great deal
    Of the eight units I have bought so far only one has what looks like minor chatter from machining beneath the ejection port that does not affect operation.
    The rest are either flawless or have minor handling marks that look like pencil lines

    Blem M4 Flat-top upper

    Great value for the money! Mine had a decent scuff down the side, but I have no complaints.

    Absolutely worth it

    This is a great value for a quality upper. Not only is it one of the cheapest options I found, but it comes with the forward assist and dust cover. I did have a "scratch" about 4" long on the side of the reciever, but it really looks like someone just ran their fingernail across it and left a faint white mark. Overall this is a great option for a build that is going to get scratched up or painted anyway. I am probably going to use these exclusively when building from here on out.

    BCM Demo/Scratched M4 upper receivers

    Great product at a great price. You might be able to tell that the two that I purchased were mark/scratched in some way but you would have to look long and hard. Well worth the price. I also compared them with a couple of other quality uppers that I have and the fit of the barrel to the upper is noticeably tighter. As Martha Stewart says of all her AR builds "That's a good thing".

    BCM UPPER RECEIVER (DEMO SCRATCHED)

    Exceptional quality from a great company. And the shipping...how did they get it to me so fast? 1 small skuff on the selector side, otherwise flawless!!! If you need an upper and you don't buy this one...your crazy and must have money to burn! As always Bravo Co is my go to for AR parts!!

    High quality upper!

    I was building uppers from aero but i was never a fan of how loose the barrel extension slides into the upper. Bcm will be the start to my builds from here on out! Patiently waiting for ar10 parts from you guys! Keep up the great quality!
