    Practically Flawless

    I wasn't expecting much. I wasn't even expecting the ejection port cover, pins, and forward assist that was included. There was barely a scuff on the finish where the charging handle would sit and on the barrel thread. Threads are still in perfect shape. The big thing is there are no BCM markings. Not that i expected it either but if you want the BCM name then you'll need to dish out the extra $. Completely satisfied with this purchase and it turned out much better than expected. I don't even need to bother looking to put another coating on the upper, I will be running this as-is.

    Best stripped upper for the price!

    Seriously the best deal for a quality upper by a quality company.

    As far as the "blems" go, i have four of these now. I could only find 1 blem each on 2 lowers, the other 2 are flawless as far as i can tell. The 2 blems i did find are super small; one was a tiny tiny nick on the barrel nut threads (doesn't affect use of course) and the other was a tiny tiny nick under the forward assist. As far as blemished uppers go, i don't mind them one bit since they're going to get blemishes during the first range visit anyways. So it's pretty much money saved for uppers that'll get scratched up during use/transport.

    I like how they don't have the white BCM logo on the side above the forward assist makes it a bit more low-key without the bright white logo on their regular uppers, they're still marked "BCM4" above the gas tube hole, which will be completely blocked by a rail anyways.

    Blem upper receiver

    It was a little dinged up, but then it is a "Blem". Others reviews I read about were not so beat up apparently, but it was a risk I was willing to take. A little more black applied, all is well. All the parts are there, good to go, lets move on.

    Well worth it

    I purchased this upper to go with my Rainier Mountain 18" mid weight barrel. Were there some imperfections? Yes. Did it look any different than it will after the first 3 gun it will go through? No. The barrel was snug fitting in the receiver, I had to hit it with heat gun to get it started. The KMR-A 15 index clip seems to marry up better to this one than my Bushmaster or PSA uppers, plus I didn't have to over-torque the barrel nut like I had to on the PSA, but it was also a different barrel so that could be the variable. It also locks up better to my Spikes lower than others I have tried. Shipping was rediculous, I ordered on Friday after business hours and it was at my door in Texas on Monday. Very happy I went with BCM instead of other options, but then again, who hasn't been!

    Uppers for the Do-it-Yourself Projects

    Could hardly tell the Uppers had a Blemish. These, are a great way to start a do it yourself project. I am definitely would recommend these uppers to my friends for their project builds. Items were well Packaged & shipping on time.

    Demo flat top receiver

    Mine have a 3" long rub mark on one side. Does not go through the finish to the metal. Can probably just be covered up with oil

    Scratched?

    This upper was perfect. There was one spot where the paint had been barely rubbed off. Haven't fully assembled into a gun, but honestly, i couldn't believe it was considered a blemished upper. i literally had to look for an imperfection.
