    Let me start out by thanking CBC for getting this upper to me so quickly. This upper exceeded all my expectations for finish, operation and accuracy. It cycles every kind of ammo (super and subsonic) I fed it with near MOA accuracy from a sandbag and red dot.

    If you are on the fence about purchasing this upper, you definitely will not regret it.

    Took the newly built rifle to the range. Three rounds in, it stopped ejecting spent cartridges. Looked at the side of the handguard and noticed a buildup of light brown material. Took the handguard off to check the gas block and gas tube, and the block had slide significantly. I could actually turn the top block screw with my finger it was so loose. I’m not sure how this could have been overlooked. Haven’t tested it out since tightening down the stews, but it appears to be fixed for now.

    Ordered two of these uppers and they are awesome. Only a 7 day lead time with fast 3 day shipping. The craftsmanship of this upper is perfect and the 15 inch CBC keymod forearm feels great. Can’t wait to get it out and shoot! Thanks CBC for the great product I will be ordering more soon.

    I received this upper assembly in a very timely manner and as soon as I opened the box and got the upper out to took the hand guard off so I could remove the barrel nut to apply anti-seize, I do this with all new assembled uppers. I was very impressed to find that they had already applied anti-seize on the threads. I have purchased 4 other uppers from other places, such as palmetto state armory, and not a single one had anything at all on them except for this one. Very pleased with this upper at 100yrds with a Nikon 223 scope and it repetitively shot groups that were sub MOA. I will be purchasing more upper assembly’s from CBC for sure.

    I ordered this upper just trying something new an man am I glad I did!! You can’t beat the price point and the quality of these uppers! I have shot all types and weights of ammo in this upper and all shoot well! Mine seems to really like the heavier bullets more than lighter. I’m am VERY pleased I went with CBC on this 300 BLK upper. I will definitely use their uppers on my future AR rifles. I will also add their customer service is 2nd to none!

    I have been interested in a 300 blackout upper for a while. Then a saw a a great deal from CBC Industries for a AR-15 Upper Assembly – 16″ / 300 Blackout / 15″ CBC Arms Keymod GEN 2 AR-15 Handguard / Rail × 1 could not pass up and placed a order. When it arrived and took it out of the box, I could not believe how light it was. I mounted it to a complete lower I already had built and loved how the slim rail felt in my hand. I mounted a Nikon 300 blackout scope and finally took it to the range a couple of weeks ago. After getting my scope sighted in at 50 yards I fired 125 grain,130 hog hammer and 147 grain bullets and was putting my bullets in the x ring every time. It was getting dark so I was not able to shoot 100-200 yards, but expect good results when I do. I had zero feeding or ejection issues with any of the ammo I used. The recoil was a little more than a 223 but a lot softer than I expected. I would recommend this upper to my friends.
