    I was the winner of the upper give away from CBC and this was the one I chose. I mounted it on a Spikes Lower with a Vortex PST scope and it is the most accurate upper I own, and I have several different brands!!!! I could not be happier and I recommend them to everyone that asks about it and I plan to purchase others in the near future. Thanks again CBC.

    I really like this upper. It has a clean sleek look. It’s fairly light and has a great feel. Only thing I’m not happy with is the quality of the anodizing on the rail. I haven’t fired anything out of this upper yet. I took it out of the box and placed it on my lower. Just from holding it(numerous times) the finish on the rail started to rub off from my wedding ring. Other than that it’s a really nice solid upper. I would deffenitley purchase another upper. I’m very happy with It!! Thanks CBC!

    Bought this upper a while back when it was on sale. Did some accuracy testing and it did ok for the price. Average group size of 2.9″ @ 100m. Worst group was 5.5″ and best group was 1.6″. Was using 62gr Federal XM855, I’m sure I could get better groups with some match ammo. Granted it’s not a precision upper, so as part of a fighting gun I think it’ll do great.
