    M4 uppers

    You have to thermo-fit your barrel to the upper, in other words, heat the receiver so the aluminum expands a bit to take the barrel extension. No more using shims or hoping you used enough Loc-tite to bed the extension. There are my favorite forged uppers.

    Can't beat the price

    Ordered 2 Demo/Scratched stripped upper receivers. they almost look perfect.. I can't really see anything but a smudge or two on them and for the price, you just can't beat them.

    I'll be ordering a few more in the near future...

    Upper blemished

    These uppers by far are well worth the price even as blemished their quality in this condition is extremely good. I have bought multiples and will continue to do so every time I find them on sale

    My first unassembled upper

    A little disappointed...I ordered scratched and can’t find a single one! BCM never delivers anything less than excellence. Fast, secure packaging, clear paperwork, tight upper, and stickers to boot. Thanks much!

    Great upper

    Came in the mail fast and was well packaged. The upper was in VERY GOOD condition. Only a few small marks and blemishes that honestly would eventually be there from use if run hard. I'd buy my upers like this again for the cost and quality. Still BCM top of the line work.

    Customer review

    I have not built it out yet but the only flaws I could find was one very small scuff. I'll probably scuff it worse than it was when I received it, the first time it hits my belt Buckle.
