    Outstanding Upper

    Well BCM has done it again! The upper was built to proper spec and had a tight neck for the barrel to slide into. These uppers are the best I've seen if your looking for true quality over cosmetic look! The upper had the proper dry film lube on the inside also. Note* you may get an Anchor Harvey forging or a Brass and Aluminum Forging based off my experience.

    Excellent uppers

    There's a reason I went with the Bravo Company upper for my build and it's the same reason I went with a Bravo Company Lower, their quality of second to none! I am very happy with my purchase and happy that I decided to go Bravo Company instead of a few other major manufacturers that I had in mind. I'm very happy with my build!

    Quality receiver

    I like the machining. Can't see any blemishes or lines from machine work. Good quality receiver, way better than original stock part. Assembled properly. Laser T markings are clean and clear.

    perfect fit

    This is the fourth upper build using the BCM M4 assembly. Barrels fit nice and snug, mates to several different lowers and the color usually matches close enough. All is good. Great upper to use, good price, no problems. Thanks guys.

    Nice product, Nice Price

    Unit came fully assembled and ready to install. Needed to use a heat gun on the barrel threads for tight tolerances with barrel. Tight tolerances here are a welcomed. I would definitely purchase this item again. Just wish it had the BCM logo on the side. But it is stamped BCM4 above the barrel nut and gas tube hole.
