Product Details: AR-15 Upper Assembly – 16″ / .223 | 5.56 / 1:8 / Stainless Steel / Bear Claw / 12″ CBC Arms Keymod AR-15 Handguard / Rail

➲ Upper Receiver

The foundation of all good AR's is built upon a dependable upper receiver. CBC upper receivers offer best-in-class quality while providing you years of dependable service. Boasting a MIL-SPEC type III hard coat anodized finish and machined from 7075-T6 forged aluminum, this M4 flat-top receiver delivers a lifetime of superior function. You want your AR built upon a solid platform - this receiver gives you the confidence that your AR-15 will function when it counts most.

➲ Carbine Gas Tube

An essential component to your AR15 is the gas tube, which keeps your build up and running. This gas tube is constructed from corrosion resistant stainless steel ensuring a lifetime of service.

➲ .750 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 nitride finish, this 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.

➲ Bear Claw 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 416-R Stainless 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.

➲ Keymod Handguard

Your AR-15 handguard has huge implications in terms of how much you enjoy your shooting experience. Our Keymod handguard offers more than just the accuracy enhancements that come with a free-floating rail. It features a full-length picatinny top rail that sits flush with M4 flat top receivers allowing you to have more space for optics and back up iron sights. The slim profile is comfortable to grip while still allowing enough room for low profile gas blacks underneath. This AR-15 handguard is machined from 6061 aluminum, has a hard coat anodized black finish, and the strong attachment of accessories to the Keymod handguard are unaffected by recoil.

➲ A2 Flash Hider

The muzzle device is designed to perform a specific task, like suppress flash intensity or reduce felt recoil. This A2 Flash Hider is machined from quality steel and finished with an exceptionally corrosion resistant salt bath nitride for a lifetime of service. It provides effective flash suppression that preserves the shooter\\\\\\\\\\\\\\\'s night vision by disrupting the muzzle flash when firing in low lighting conditions. While its closed bottom with top and side ports offers reduced dust signature when shooting from the prone position while additionally acting as a compensator.

  1. Rick Summers

    I would like to say that CBC Industries is a world class AR-15 distributor. This was my first experience with ordering from their website and was a little nervous about doing so but after the super fast shipping and wonderful customer service department I will definitely purchase from them again. First Class packaging to ensure the product arrived just as it shipped. Thanks again CBC Industries for the easy transaction. I am more than extremely satisfied with my order.

  2. Ruben

    Got my upper in about 2 weeks. It is alot better than i was expecting. I couldnt decide which one to get. So i will buy another 1.

  3. Logan

    I am very happy that I went with this company over the others I was looking at. Very fast shipping. Will definitely buy from here again.

  4. Jaime Cerda

    This upper receiver was shipped sooner then what I expected. I bought a lower receiver (E3 Arms Omega-15 AR-15 Black Polymer Complete Lower Receiver) at my local gun store here in CA. I was kind scared of buying this upper receiver online but when I got it I felt like a match maker. All I can say that it was love at first site like a perfect marriage meeting all expectations. I took the AR to the range and performed like a stud. All my friends that have AR’s are hating with this good looking gun. I would definitely do it again. Thank you & God bless to all the hard workers at CBC Ind

  5. FRED

    I looked at a lot of uppers but decided to go with this one because it had everything I wanted at a fair price. Everything fit right and looks amazing. I am for sure gonna order again!

  6. John Doe

    Excellent craftsmanship. Nice melonite finish. The bear claws look beautiful, and it did cool down quickly. Shot my first 88 rounds of cheap brass .556, no jams, no failures to feed, no nothing, with a WMD BCG with a light spray of WD40. I had my new magpul rear sight on backwards so I couldn’t quite say but it did seem accurate at 300 feet, no fliers. The front bottom RIS rail is a bit too forward for a foregrip, but it’s handy it comes with those anyhow. I’ll have to get a keymod RIS piece for that. It wobbles a little attached to my PSA lower, but who knows who’s to blame for that – Some shims should fix that up. Not much else to say cause I’m just a noob but yeah this upper is excellent, imo. And the company was awesome about keeping in contact, 2 day shipping, let me know when it was ready, shipped it immediately after that. They were promptly honest about not having the 1:9 twist in stock, so I got it in 1:8, even better. Took about two weeks for them to build it and ship it from when I ordered it; that’s agreeable imo.

  7. Joel Bustamante

    Finally got a chance to take my new build out to the range and was very happy with this upper! I did have a few failure to feed issues and judging by the direction of the ejections I believe it may be undergassed slightly, though it could just as easily be the magazine. overall build quality and design is excellent. after sighting in it was consistently accurate. I am very happy with the upper and am confident the feed issue will be easily resolved. I will be purchasing more uppers in the future.

  8. Ryan Hurtz
