    I initially bought this upper to see what all the fuss about .300 ammo was. I chose this upper because it looked different in the fact that the hand guard was almost the length of the barrel and the price was reasonable. I received the upper, mounted it to my lower without a hitch, nice tight fit. Took it to the range, ran some ammo through it and found it to function as good as it looks. Even got a few nods of approval from the range officers. Overall I found it to be a great upper at a reasonable price and runs without problems. In fact I liked it so much a bought two of them.

    Just received this 300 upper, my third one in the last two months. As usual everything was clean and cosmetically perfect. I can’t believe the excellent product along with the great promotional deals. The sights I ordered were back ordered but all other commitments were made. I put 100 rounds through the upper with muted sound due to the super Hera linear compensator. Supersonic ammo really pops though.

    I have purchased and reviewed 2*160-990 last year and they are excellent uppers. I’ve put 2k rounds through already with new hiccup. This time I came back to CBC for AR pistol build. I thought about going for 7.5 upper, but decided on 10.5 instead. They did not have the upper I was looking for. This model 160-550 is exactly how I want my upper, but difference is in 223/556 caliber. I messaged customer service and Lorraine Logan was able to to help me. Thank you again Lorraine, if your reading this thank you so much for working with me on my custom build and being patient with me through the whole process. Lorraine informed me that since it was not pre built like model 160-550, I would have to get it customer ordered, to fit all the parts for 223/556 Caliber. It wasn’t long before I get the invoice back, with detailed list of all the parts, price, pictures and total with everything. I placed my custom order on Dec 21 and received it Dec 23, just in time for xmas.

    I have built my 10.5 Ar pistol build, brought to the range to zero mbus back up sites and went back to zero my red dot. Fit, function, build quality EXCELLENT!!! I expect nothing less when veterans are building these for Americans. I’ve put a total of 1000 rounds already through my AR pistol and I’m extremely happy with the results. I am once again the envy of all my friends and gotten alot of looks at the range. Go ahead, buy with confidence and pull the trigger.
