    Assembled right up to my custom lower just fine. Went shooting yesterday and everything cycled just fine. Never tried to disassemble my unit but will need to when it goes to be ceracoated at the very end. Hoping I don’t have assembly problems like another Customer did. So far so good. Will likely buy another one when they go on sale. Great buy so long as the quality stays there.

    Great upper. Nice finish. No machine marks. Very lightweight. Rail very securely mounted. Gas block secure. There is a slight drop on the picatinny from the upper to the rail. The drop is accurately represented on the photo of the upper above. I have shot it without any issue with both steel and brass case, .223 and 5.56. I like the barrels too. Have received multiple compliments on the appearance. I put it on a nice lower I had waiting around. This is my 3rd upper from CBC and probably my favorite.

    I was a bit hesitant to purchase this AR upper due to the 2 star review below. It was the only review at the time. Shipping time was about two weeks before it was sent out which is inline with what the website told me when I ordered. It arrived in two days via USPS encased in a foam block to protect it, in other words it was packaged very well. I mounted the upper to a PSA lower, the fit is perfect with no gaps and the rail is flush all the way down. I had two very small tool marks but to me this is not an issue, my guns get used and are not show pieces. A bit of coloration difference as the upper is solid gloss black and the lower is more of a matte black. I used an Anderson nitride bolt and basic charging handle. I couldn’t be more pleased with the performance. I ran over a hundred rounds of the cheapest ammo I had which is steel cased Russian .556 to sight it in and test its performance, not one flaw. It cycled smoothly from the first casing to the last. This is my second AR and I would put it up against my more expensive one that cost twice as much any day of the week. To add a bit of grip to the rail I used Bravo Company keymod grips which had to press into the Keyholes but are effective at helping add a bit of hand grip on this slick rail.

    I had bought this upper a few weeks ago. I just finished building the my ar. I bought the item while on sale Labor day I think. the item had a few marks on it where I would call blemishes. so I think the item should had been mark as so. however other than that the item was in great working condition and functions just fine. Other than the scuff marks on it or if it had been marked blemished I would give it 5 stars. The scuff marks will not stop me from buying from cbc again. The item was shipped out to me faster than expected.
