    BCM Upper Receiver Demo

    I just purchased my 3rd upper receiver under the designation of demo/scratched. I don't see it. BCM makes quality stuff, end of story.

    Impressed with the quality

    I'm impressed at the quality of this upper from BCM if this is the blemish item you can imagine what a regular upper looks like from this company, the anodized finish is the best I have seeing on a upper receiver it's nice and smooth not like the other regular uppers that I have owned from different companies, I guess today I found out what a really mil spec upper is supposed to be, very happy with the product, thank you BCM and merry Christmas to all of you.

    Stripped Upper

    Ordered a 14.5 inch Faxon gunner barrel. Absolutely WOULD NOT fit into the reciever extension. Had to machine the extension to accept the barrel.

    Best deal out there

    This upper was nearly flawless besides a tiny scratch on the charging handle catch and that is not worth complaining about. Since I intend to Cerakote all my builds this is the most awesome budget alternative and these will be the only uppers I purchase.
