Product Details: AR-15 Upper Assembly – 10.5″ / 300 AAC / 1:8 / Linear Compensator / 12″ CBC Arms Keymod AR-15 Handguard / Rail
➲ AR15 Linear Compensator
This AR15 Linear compensator works very well with any AR style pistol or SBR. This compensator helps to mitigate concussion while helping to reduce flash. The inside was designed with 12 expansion chambers, letting the gases expand and dissipate, making shooting in close proximity a much more enjoyable experience for everyone involved. Generation 2 has been manufactured to be 30% lighter when compared to the previous version. If you\\\\\\\'re running a shorter barrel and don\\\\\\\'t want the nasty concussion associated with muzzle blast from a stubby barrel, this linear compensator won\\\\\\\'t let you down.
➲ 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.
➲ 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.
➲ 300 Blackout Barrel
The barrel is one of the few components that directly affect the accuracy and weight of your build. This barrel has a parkerized finish for increased strength and durability. This provides not only an impressive barrel life but ensures excellent accuracy. This barrel is optimized for stability with a 1:8 twist rate, making it the perfect match for the 300 Blackout caliber.
➲ 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.
