    Demo/Scratched M4 Flat top Upper

    I believe BCM makes the absolute best upper on the market, and these are a great value. I have purchased over a dozen, and I am yet to get one that has a truly noticeable flaw.

    Clean and snug

    Still need to run the first shot through it. The only flaw on it is the one I made installing the dust cover spring. As long as it functions on the range I will buy more

    A Great Purchase

    Upper is in excellent condition. Not even sure where the blemish is.

    Quality

    I searched closely for a “blem” and was not able to find anything on the upper I received. I wouldn’t hesitate to buy another.

    This is second one I have bought and they bothe have no issues. Look brand new to me but they are sold as I guess blemish with handling marks and such. Best deal for best upper on market

    Upper receiver

    Great upper receiver has the tightest tolerances I’ve used. These are Blem but you have to look really hard to find the flaws.

    Demo/Scratched Upper (Where?)

    What I received was New, Unscratched, Quality upper, perhaps the only thing that made this a demo upper is the absence of BCM letter markings, but the star and bcm4 markings are there so I’m sure this is a BCM upper.
