Product Details: AR-15 Upper Assembly – 24″ / .223 | 5.56 / 1:8 / Spiral Flute / 15″ CBC Arms Keymod AR-15 Handguard / Rail
➲ CBC Keymod Handguard
New for 2020, these AR15 handguards are built to provide rugged, reliable performance. Designed with the advanced shooter in mind, these AR handguards are both sleek and ergonomic in the hand and that translates into faster on-target performance and ease of use. These AR handguards provide Keymod slots for mounting attachments and feature robust steel mounting hardware to ensure an easy rock-solid installation.
➲ .936 Low Profile Gas Block
The gas block is a critical link in the chain that is too often overlooked. This component ensures that your AR runs reliably. Made from high-quality steel with a smooth phosphate finish, this .936 low-profile gas block is efficiently designed to stay put with the percussion of gunfire. With its low profile, this gas block allows it to fit under the most ergonomically designed handguards and rails on the market.
➲ Rifle Length Gas Tube
An essential component to your AR15 is the gas tube, which keeps your build up and running. This rifle-length gas tube is constructed from corrosion resistant stainless steel ensuring a lifetime of service.
➲ Spiral Fluted Barrel
The barrel is one of the few components that directly affect the accuracy and weight of your build. Designed for corrosion resistance, this barrel will not let you down. Due to being machined from 4150 chrome moly steel, this barrel contains a better cut, higher-definition rifling, crowns, and chambers, resulting in the ability to stay more accurate over its usable life. This barrel utilizes the popular and versatile .223 Wylde chamber, which allows for the safe usage of 5.56 NATO ammunition and enhance reliability. This is the perfect barrel for an AR build, keeping weight to an absolute minimum due to the fluting, while still offering a significant ballistic advantage.

This upper receiver exceeded our expectations for workmanship, fit and finish, materials, and great customer service. We searched the web for a target grade upper receiver for several days when we found CBC. When we contacted them by phone, the representative was extremely knowledgeable regarding his products, and recommended the addition of the charging handle and bolt; both of which were excellent. He explained the product, return policy, etc.
The product was shipped in discreet packaging with a non-recognizable as a gun part return address. When we opened the package we knew that we would not be returning the receiver. It looked great.
We installed the upper on a Sig-Sauer, where it went together perfectly. As a result we bought the rest of the parts, put the Sig back together, and now have two AR’s.
The upper was so well made we have recommended CBC to our friends. Similarly, we have no intentions of ever purchasing a completed AR. CBC is the way to go for the starting upper.

This 24″ barrel complete upper is legit! Upon close inspection I could not find any flaws at all. I am very happy with this purchase to add to my ar-15 collection. However, kind of disappointed that CBC Industries had no company stickers for me. I recommend this made in the USA product you cant beat the value.

I put this on my Anderson lower with a Palmetto lower kit. It fit perfectly. The assembly of the upper seemed perfect after careful inspection. I really like the slim keymod rail. It shot perfectly too. It is an excellent addition to my collection. I will be back for more .

Great upper! Can someone tell me what the thread pattern is on this barrel?

Yikes this thing is Awesome!!!! Beautiful from top to bottom and front to back. Only negative it the lead time on this item. I received it 20 days after paying for it. That was un expected, but it sure is awesome. Highly recommend for prairie dog and coyote long range hunting. Thank you CBC for a good price and a great product. I do tell my friends about CBC and will continue to buy from them. 🙂
Chris Wright –
This upper came in on time (thank you Lorraine!)
No flaws looks perfect!
(Thank you CBC)
Took it to the range 3hrs after it came in, kicked the tires, tried 5 different makes of ammo (200 rounds)to see if I could find a flaw….it stood the test! I will definitely buy my next upper’s from CBC ! You cant beat the quality, price, and service!

I ordered my upper on Labor Day weekend and the delay was shown as 7-10 days out. There must have been an increase in demand for that time as in the next week, lead times increased to 3 weeks. I waited 3 weeks and called to find out the status of my order and was told that it was delayed indefinitely due to the handguard being out of stock. It would have been nice to have been contacted. CBC offered to get a Hera handguard on and ship asap. It arrived a week later with assembly marks on the barrel that I could have lived with but a ding in the crown that I could not. Sent it back for 2.5 more weeks of delay. Shipping was promptly reimbursed. New barrel arrives with minor assembly marks, weak spots of barel finish. Handguard is good quality with the exception of an over torqued Allen screw and a new handling blem (second trip) covered with Birchwood Casey black coverup pen. At least it was covered up. Forward assist assy pin has a double strike in the reciever but it’s underneath. My hardware is to be used as tools and function is prized over aesthetics. Function and accuracy are good. I have already bought from CBC again. I assume the diminished QC is related to the increased lead time. A growing company has growing pains. Thanks guys!

I ordered this upper with semi high expectations and boy did it deliver. This upper grouped 3 shots in less than a dime with 2 different types of store bought ammunition. I can’t wait to fine tune this rifle with some hand loads that it likes! Shipping was supper fast and I have several lowers that will be getting some new CBC uppers soon. Also like the fact that there from down South. It’s a win win for me.
Mr B –

This is a good quality barrel and its accuracy is beyond what I was expecting. I confirmed its accuracy by shooting it with iron sights at 100 yards. 1 MOA in average. I will save you the time and money by telling it likes PMC 223 Bronze 55 grain, PMC 5.56 XTAC 55 grain, Federal 5.56 55 grain and MEN 5.56 56 grain (It loved MEN the most). I can officially say I will purchase more items from this company in the near future.

Upper arrived in a well padded box. The quality of the receiver and the handguard are great especially for the price. Machining and finish on the barrel look very nice. I will shoot it this week and update the post on its accuracy with multiple loads. Thanks CBC!
