Product Details: AR15 Upper Assembly – 20 Inches / Bull Barrel / 223 WYLDE / 160007

➲ .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 aluminum 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.

➲ Rifle 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.

➲ 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.

➲ 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.

➲ Bull Barrel

This barrel delivers superb accuracy by increasing rigidity, decreasing harmonics and dramatically reducing felt recoil. A favorite among long range and varmint hunter enthusiasts, this 4150 chrome moly steel barrel features a heavy profile designed to accommodate .936 gas blocks. This barrel features a .223 Wylde chamber, giving the distinct advantage of being capable of shooting .223 Rem or 5.56 NATO cartridges.
