    Stripped Upper Blem

    Nice item. Bought this because my 'go to' had not had uppers (blem or otherwise) in ages and I wanted to get on with the build. The day before I started the upper build, my 'go to' FINALLY had their uppers in stock. I will pick up a BCM lower (best to match receivers) for my next build, which will be a 6.5 mm. It will be good to have a different company for the different calibres.

    Upper

    Can't find the blemish anywhere! Upper and barrel were a super tight fit but I would buy again, and likely will in near future!

    Awesome Demo

    Upper looks great. Looks even better with the fluted barrel installed. First time purchase from BCM. Fast shipping, received in 3 days. Cant wait to complete my first build. Will definitely buy again to build a 300 blackout.

    Solid.

    Used this upper with a Colt SOCOM profile 14.5 inch barrel. Barrel extension mated up flawlessly with no play whatsoever. Very tight, nice even finish. Matches my Colt lower very well. No receiver wobble at all.

    Will use these on all future builds.

    BCM Upper Receiver DEMO/Scratched

    Fantastic bargain; I bead blasted and sprayed KG Gunkote on the upper, and port door which really did not need refinishing but I wanted the upper and lower to have the same finish, good price, excellent shipping, and service as always. Thanks Bravo for the excellent products
