    Blem Upper

    The upper I received (in just a couple days) had a 1 inch long, very light scuff along the right side. I couldn't find any other blemishes at all. inside or out. It was immediately evident this was a top quality piece. The fit between the extension on my 20" BCM barrel and this receiver was very tight requiring a little heat to get it properly seated. This turned out to be the most accurate Mil Spec AR 15 I've owned to date easily shooting 3/4 MOA with the IMI 77 grain MK262 clone. I would definitely recommend this upper receiver to anyone looking for a real quality part for any rifle other than a safe queen.

    BCM Upper Receiver - M4 Flat Top Demo/scratched

    I've used these uppers for a number of builds. The uppers look good as new to me! My rifles are working guns not safe queens, so saving a bit of money and getting a superior product in the bargain, is a big win win!

    excellent customer service.

    I purchase a couple of blemished uppers for my next builds. The uppers are in great shape, just goes to show how good BCMs quality control really is. Very impressive processing and handling times as well, had them to me in 2 days.

    "Demo/Scratched Upper Receiver"

    Ordered based off the company reputation and reviews from other commenters/YouTubers. I ordered the "demo/scratched" upper receiver for $80. Arrived super fast and I could only find one small mark on the upper receiver that most people probably wouldn't even notice without looking real hard (it was inside one of the picatinny ridges). Will order more BCM stuff in the future. Plus, Veteran owned company. Semper Fi!
