➲ Carbine Gas Tube
An essential component to your AR15 is the gas tube, which keeps your build up and running. This carbine-length 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 .750 low-profile 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.
➲ Upper Receiver
The foundation of all good ARs is built upon a dependable upper receiver. CBC upper receivers offer best-in-class quality while providing you years of dependable service.

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.
➲ Colt Competition Style 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. While featuring a special contour that is designed to be lighter than a conventual SOCOM barrel giving you that extra edge when shooting 3-gun competitions. This barrel offers a 1:8 twist rate, suitable for both heavy and light ammunition. It is corrosion resistant resulting in an extended barrel life that is longer than conventional chrome lining. Thus, being the perfect barrel for long distance shooting, competitions, hunting and practically any shooting application you’ll subject your AR-15 too.
➲ AR15 Muzzle
Not all muzzle devices are created the same. There aren\'t many muzzle brakes and compensators that \'understand\' proper high-pressure gas dynamics. This AR-15 Muzzle Brake has a three chamber design that significantly reduces muzzle rise. It has 1/2x28 threads, so you can attach it to your favorite 5.56 or .223 barrel and finally finish that build you have been working on. It is made from high-quality steel and features a durable phosphate finish that will look great on any AR build.
