    M4 demo

    Great piece, in great shape. Virtually new condition, perfect fit with barrel once you apply minimal heat from heat gun as is recommended during all new receiver/barrel installs.
    Would buy another when needed, great service and very fast delivery on all parts.
    Thanks for the sale

    BCM Upper

    The upper came packed well and all small parts were included. Upper fit very well with a Anderson 10.5 5.56 barrel and Anderson lower. The finish was very good with a couple of small nicks that are not visible when installed on the firearm.

    The upper I received is a Anchor Harvey forge with BCM4 stamped above the gas tube area on the front of the upper.

    I hope to get another one when they are in stock again for another build. Thanks BCM, I'm happy with my first purchase with you all.

    BCM Upper Receiver M4 flat top Demo / Scratched

    I received my demo / scratched upper receiver and could not tell where the blemishes were, I would buy another one for the price.

    2 out of 2 were perfect.

    I've purchased two of these several months apart from each other. The first one had absolutely no blemishes. The second one had a long white streak. BUT no fear! It wiped right off with some Mpro 7. It had no imperfections in the actual finish. I will continue buying these uppers over any other for my builds. Tight tolerances, cheap price, BCM Quality, good finishes, Good to go!
