  1. Rated 5 out of 5


    For being sold as a blemished upper, this thing looks great! I could not find any marks or dings on mine. At this point, I have only used iron sights, so I can’t really comment on accuracy, but it has digested every type of .223/.556 ammo I could find. Even the cheap Russian stuff functioned flawlessly. Overall I am very satisfied. Can’t wait to add a decent scope and see how it performs at 200 – 300 yards.

    This upper makes a very nice rifle. I could not find any blemish, looks better than a nother rifle that I paid $1,000 for. It also shoots great. It is heavy, I used $35 of the money I saved on a muzzle brake and it stays very stationary. It delivered in exactly one week. I will buy from CBC again.
