➲ 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.

➲ .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.

➲ Pistol Length 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.

➲ Barrel

The barrel is one of the few components that directly affect the accuracy and weight of your build.  This barrel has a nitride finish for increased strength and durability. This provides not only an impressive barrel life but ensures excellent accuracy. The barrel threads are carefully threaded to the .308 standard. Optimized for stability with a 1:8 twist rate, this 300 BLK barrel can handle heavier bullets used for subsonic loads with ease. 

➲ 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.

➲ M-LOK Handguard

Your AR-15 handguard has huge implications in terms of how much you enjoy your shooting experience. Our M-LOK 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 generously sized M-LOK cuts for air circulation.

  1. dan-o

    Having an itch to build my own AR I chose the CBC to support our Vets and the ‘Made in USA’ concept. I was extremely satisfied with the fit, quality of workmanship and function of this upper. After reading horror stories about other affordable uppers from other companies, I was a little apprehensive of what kind of quality I could afford. I have NO issues with this upper. It went right together on my Anderson lower. No tweeking needed. Fired straight. No function issues at all. The finish was perfect. I WILL buy from CBC again.

    Took it out with a new batch of reloads and rang the metal gongs immediately. Super accurate and worked flawlessly. Keep up the great work!
    2nd upper already ordered.
