    Excellent Buy

    Don't anyone buy these. I want the rest. If mine were scratched or out of spec or used there was no obvious indication. These went together perfectly and fit all of my lowers without a wobble.

    Product came in perfect condition

    Being advertised as a blem unit I expected some scratches. But not a mark was on it, was a perfect piece for a 16 inch build I'm doing

    Stripped upper

    Received this very fast! Excellent condition. For a scratch and dent...I can’t find a mark on it! Mine will be used for a MK 12 Mod 0 build in 6.5 Grendel. The upper should work perfectly.

    Thanks BCM for a great deal on a quality part!

    Arrived as i expected, large scuff mark on left side and a few nicks. Black paint pen fixed most of it. Same great BCM quality at a fraction of the cost of other uppers. I will definetly buy again.

    Awesome upper especially at that price. Used on for 300 blk and one for 5.56 build. They function flawlessly, are accurate and the mil spec dry lube is icing on the cake. Will definitely be getting more for future builds.

    Great upper for the $...by far!

    Had this upper recommended by a friend who has immense amounts of experience with gas guns, professionally and competitively. It did not disappoint in any fashion...still haven't located the "blem", but I'll take that any day. Unlike most "run of the mill" uppers, the BCM upper was recommended to me because of the slightly undersized dimensions where the barrel extension attaches. Had to thermally fit my CLE barrel, just like I was hoping. Very tight lock up = improved accuracy...highly recommend these uppers!
