    Best value

    I can't believe it came with all the parts. And more stickers then I thought for a stripped upper will be buying more straight from BCM , seriously home run. Absolutely shocked for a first time order. Mine wasn't too beat I was hoping for better but I signed up for a blemish looks more like a finish issue vs gouging

    M4 Upper Blemished

    I bought this upper knowing it would have a dent or a scratch but all I could find was a small mark in the coating. I can put up with a tiny mark for the money saved. I highly recommend this if your in the market for a good quality upper.

    BCM Blem Upper Receiver

    I order this item after reading many reviews, mostly positive. Received the item very quickly and was surprised at the condition it was in. I expected scratches or tool marks all over the surface but after installing it and cleaning it up there were absolutely no noticable defects
    Really loved how the barrel extension opening is slightly reduced so that the barrel is extremely tight locking everything together. Plan on switching all mine out now to BCM.

    Blemished uppers

    I could not find a blemish anywhere on the "blemished" uppers I purchased. I measured the inside dimensions of the area where the AR 15 barrel extension fits to the receiver and found it to be .003-.004 tighter than 2 other uppers I have on hand waiting for builds. Exactly what I was looking for and expect from BCM. Buy these with confidence, best upper deal on the market right now.
