    Seems good to go

    Haven't fully assembled the uppers yet but the barrel fit is tight on the two I received and all else appears good to go. The only issue I found on both receivers was some very minor scratches on the barrel nut threads and the manufacturing mark by the forward assist isn't really legible. I can't tell if its an A, M or a square. I think its the Muller emblem because that is what is on a previous no blemished reciever I got. Otherwise all as a appears fine.

    blemished upper?

    for a product that was marketed as "blemished", I could not find ANYTHING wrong with the upper. the attention to detail on the end of the receiver threads (lapped and squared) and the tight fit make a wonderfully accurate rifle! How can you miss a hit with this!!!. great shipping, great deal. Thank you Bravo Co.

    BCM Upper

    As far as I'm concerned BCM uppers are the best around and I won't build a serious use gun without more than a few of their parts. I chose the blem option since I couldn't get the BCM markings proper outside of a complete upper anyway. Paying the extra for an upper that I would likely scratch and/or rattlecan down the line seemed like a no-brainer to save a few bucks.

    Sincerely,

    A satisfied customer who will continue to use and recommend these parts to anyone he knows.

    best stripped upper. why pay 3 x for a colt

    built 4 rifles with this upper. the tolerance is very tight, but that is what makes me keep coming back. just make sure to heat up the barrel extension with a heat gun.
    gives colt a run for its money especially in price.

    BCM blem upper

    Ordered it over a weekend, shipped Monday, had it in my hands Wednesday. That's fast service! The only flaw I could see was the anodizing on one side was a touch off, no big deal. Barrel fit was excellent. Just had to warm the receiver with a hot hair dryer and they went right together. This finished my 6mm AR build that shoots lights out! Thanks BCM!

    Deal on upper (Demo/scratched)

    I have purchased from BCM several times and never been let down.
    With my latest AR build I needed something that I would be gunkoting and not concerned with the finished
    The stripped upper scratched demo version was a deal I couldn’t pass up.
    Showed up with about a 4” long surface scratch on the left side, again I would be sandblasting to a raw finish and applying gunkote so it didn’t matter, but for someone with some time may be able to put some elbow grease and hoppes at the scratch and minimize the damage
