    M4 upper demo

    It was shipped super fast (within 2 days of order), and it was absolutely unblemished for a demo unit. I'm actually going to order another, maybe 2.

    Best value

    Not going to lie, fitting with this upper is a new process if you are used to cheap uppers. I used a butane torch to lightly heat the threads, and then I could insert the barrel about 75% of the way into the reciever. The barrel nut did the rest of the work and presses it into place.

    Great deal on great quality upper. Can't find any blems at all.

    Excellent Upper

    Receiver shipped pretty quickly. Fit with my Rosco MFG barrel was nice and tight, but not impossible to put on. Tighter fit to my SR-15 lower than my previous Aero upper. As far as blemishes go, this one has some barely visible marks on the rails, but nothing really noticable.

    Blemished upper

    Went together without a hitch. Couldn’t find a mark on it anywhere.

    Blem upper

    Outstanding upper for the money. On my upper the only thing wrong with it was the color. It was more a charcoal color.

    M4 blemished upper

    very happy with my purchase. In the process of building three complete BCM uppers and will be using these on all of them! I appreciated the quick service and shipping and BCM has definitely earned my business thus far.
