    Dust cover required modification, Barrel reciever

    I understand it is a blemish upper and overall I am happy with the product. However, it would have been nice to know before purchasing that I needed a heat gun to install the barrel. I do not own a heat gun, thankfully I was able to borrow one from my neighbor. Additionally, the dust cover would not close due to the button contacting the upper too high.

    Looked great minor discoloration where they rubed in shipping, receivers are really tight and parts fit good

    Flawless except the flaw.

    A tiny blemish (it was sold as a blem). Otherwise perfect part. Would buy again, especially for the superb price for BCM quality hardware.

    Bcm blemished receiver

    Great product,, ordered one, it was so nice I ordered another one,, the blemishes looked like a pencil mark about a half inch long on the smooth side,,a little rubbing and you can hardly tell where it's at,,and they were both at my door within 3 days.. barrel fitment is tight,, BCG works smoothly,, don't hesitate to buy...

    Go to receivers

    BCM say they are demo/marked up/scratches etc. so it was no surprise when you get one that it has dome cosmetic faults. I have bought these before that looked perfect. Luck of the draw I suppose. Either way, I build ARs to shoot and use, not as wall hangers, so, these are great receivers for a build and the extra tight barrel mounting is very welcome. You need to warm it up a bit to get the barrel in.

    Upper

    Lightly blemished as advertised but has no function issues. All in all a good upper to build on.
    I can honestly say I recommend this product ! Plus, it's a great cheap way to go if your building something rad or a beginner at building.

    Absolute best bang for your buck

    I have bought two of the uppers in the last few months and could not be happier. Both were in stellar condition and have functioned flawless in both my builds. Both uppers have wicked tight tolerances and it was almost annoying to get the barrels seated. I will most certainly be buying more!

    If ya don’t mind the lasered logo not being on the upper get it mine had a place in the side about 3” long hot with a fine scotch brite pad looks perfect after about 30 seconds no other marks on it if I could afford more of these uppers I would have gotten them

    Can't beat this deal!

    Bought the "scratch and dent" upper. Upon arrival it had a mark on the side that looked like someone ran a pencil down it (likely an aluminum rub). Wiped it down with some Hoppe's and the mark came right off. Dust cover was bowed a little but it was easily straitened out as well. It's practically a new upper for half price!
