Product Details: AR-15 Blemished Upper Assembly – 20″ / .223 | 5.56 / 15″ CBC Arms Gen 2 Keymod AR-15 Handguard / Rail
➲ 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.
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.
➲ .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.
➲ 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.
