    Super bargain

    Great bargain and as far as a blemish it looks great to me not a problem with it at all.... Thanks BCM for great quality products!

    Excellent quality

    While I was able to find the blem it was inconsequential. There were some machining marks underneath the finish. The marks were under the ejection port and with the dust cover installed are not visible. I was impressed with the quality and the barrel I used was a tight fit without having to use heat. Highly recommend the blem uppers. They will be all I use on future builds!

    Good quality

    Had some cosmetic scratches... but it's a demo/scratched so I was hardly surprised by that. Barrel was a VERY tight fit as I had to put the receiver in oven and the barrel in the freezer to get them started. Then had to use a piece of wood and a rubber mallet to get it the rest of the way in. Parts were missing as well, but bravo was quick to get them sent out after I notified them. All in all I am happy and if they have them in stock next time I am building I'll get another.

    Blemished upper

    Couldn't be happier with my purchase. Blemishes are not even noticeable. Can't beat it for the price.

    Works Great!

    Received and was only slightly blemished. Scratches buffed out easily. Barrel receiver was VERY Tight, as BCM specifies this is on purpose to make an accurate rifle. I needed to Grease, Heat and then tap the receiver onto the barrel with a rubber mallet. Shot my new upper this weekend and was hitting 4" plates at 130 yards with now issues.

    Excellent

    I use BCM uppers exclusively in building precision ARs. The tight fit for the barrel extension is a must-have

    M4 flat top unassembled upper receiver Demo/scratc

    The upper I received was way beyond my expectations. I couldn't find a scratch on it. I was also surprised that I received the forward assist and dust cover with it.

    Demo Upper Rec

    Superb value for price! Nice and tight barrel opening for better accuracy (used the Mrs hairdryer and aeroshell grease to seat properly)
    Could hardly make out any dings or scratches, and nothing that one day at the range wouldn't added.
