    Ok first off product is good quality ordered to compleete uppers 16″ with a 1×8 twist and 13″ hand guards no real problems noticed other than a few dings nicks and scraps in anodized coating exposing the metal. Now granted I have not been able to take it to the range to test function so things could be different after that. Now I do have some concerns one being that none of these uppers are being test fired prior to shipment to verify proper head space. Secondly was never sent any information on tracking had to go to the website and look up order to find info. Customer service is ok they are willing to work with you but there is a lack of communication in the company because things don’t get followed through when your told there gonna do something now that being said the did comp me a pair of their flip iron sights which are very nice quality. All in all it was an ok experience there were some difficulties but for the most part were able to work things out. I am a little on the fence about the company I think they are growing a little to fast for there own good and hope they can work out these minor kinks would be willing to give them another shot in the future to hopefully improve this review.

    I have purchased multiple items from CBC but this time around the service, product and delivery time was very mediocre. I received my rifle kit around 2 weeks late also the kit I received was not what was pictured or what was in the description. I was pretty disappointed so I contacted them and that really didn’t help I understand with recent events and production demand but you just can’t skimp on quality especially when you are already late on delivery. Would like to give CBC another shot but I’m kinda on the fence.

    Order to delivery time was as advertised. Unlike the other reviews, I did receive emails indicating my items were shipping and tracking information was provided. In fact, I always have. The upper looks to be perfectly aligned and the BCG and charging handle are very good quality. There are a couple of small nicks on the upper from assembly, barely noticeable, but this does seem to be a common complaint in the reviews. Overall, I give the complete upper 5 stars. The parts kit is a bit of a different story and I want to be fair here, but it is what drags the overall rating from 5 to 4.5 stars (which obviously I can’t do). I think when you look at the price for a complete upper and everything you need to build the rifle minus the stripped receiver, you probably can’t expect top quality, but the shoulder stock has issues and really doesn’t adjust easily, the retaining pins were rough on the channel edges and I had to file these a bit and the bolt catch was forged in such a way that there was still excess globs of metal that had to be filed to get the catch to fit into the receiver. (I want to stress I checked the catch with six different lowers and all had the same problem). Again, I think for the price I paid I still received one heck of a rig and I’m not disappointed with how my build turned out. I especially think this is a good item for those who are building their first AR from the ground up. Again, in fairness, 4.5 stars on this one.

    This was my second rifle built using a CBC upper, but was the first full rifle kit I purchased from them. First, the upper assembly finish was nice with no marks or flaws. However, the gas block was not installed correctly and the rifle would not cycle fully until I adjusted it and seated it against the barrel shoulder properly. Also, the shroud rail did not line up with the upper receiver rail. It required more movement than could be had just by loosening the shroud mounting bolts. I had to remove the shroud and adjust the barrel nut slightly to get it right. Other than those two items, I was very happy with the upper assembly. The rest of the parts were so-so mil spec parts. Nothing to write home about. The barrel catch had to be hand filed to fit in place and the stock is a little sloppy on the buffer tube, even with the set screws snugged up. Trigger feel was not great, but ok for a plinker. Also, my lower parts kit was missing the disconnect spring. All in all, with a few adjustments here and there, I am fairly happy with the end result and would purchase this kit again. It is a good value.
    It did arrive very well packed and undamaged.
