    Great fit

    I’ve built several ARs, but this was my first BCM upper. Everything went together well, and I loved the thermal fit for the barrel extension. This item was sold as “blemished”, but I found nothing wrong with it. I will definitely purchase BCM uppers for all future builds.

    Nice tight upper; don't know why blem

    The upper parts kit wasn't quite right, which was immediately corrected when I contacted. Would buy again without hesitation; heck of a good deal, good parts, and a good company.

    Blem Upper

    Purchased a blem upper, had slight color variance in two spots....SO WHAT!!...it comes with the dust cover and forward assist so now I have the upper to continue my build. This is a no brainer purchase and i will continue to purchase , as i save up for my build, from BCM.

    BCM Upper Receiver - M4 Flat Top (M4 Feedramps) Co

    As far as the product it was as expected. Cant say much since its a toss up. But the orders were fast and well worth the money. They were demo uppers so as far as standards i cant give an input cause BCM knew what they sold and i knew what i bought. But as for my QRF rail. I cant say enough how happy i am for that purchase. Ive been looking for the perfect quad rail and i can say BCM filled that nitch. Looking forward to making more purchases through BCM.
