    This was the second upper I have ordered from CBC and they made me a loyal customer with this one! When my upper came in in the amount of time they stated (3weeks at the time) I found a slight issue with my barrel nut, when I called them there was no delay in shipping me a replacement immediately. this mid length upper is one of the smoothest cycling I’ve ever shot, and WOW at the accuracy! With 75gn hornady I shot 3 groups of 5 @ 100 yds and all were under an inch! I’ll take that! Thanks CBC! Your uppers and customer service are top notch!
