➲ 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. 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.

➲ 45 Degree Offset Sights

Even if you have a high-quality optic or scope on your rifle, it is important to have a set of back up iron sights mounted to your receiver and rail just in case your optic fails. This 45-degree flip-up rear and front sights are designed to stay out of the way when you don’t need it and quickly deploy when you do. It is precision machined from aluminum and features a matte black finish so you can be sure it won’t break or rust in harsh conditions. This backup sight is angled so you can quickly transition between your optic and iron sights depending on the situation. This style of canted iron sight is popular with 3 gun competition shooters who have to quickly change between long-range and close targets. It is quickly deployable via a positive lock button that, when depressed, locks the sight tower to prevent it from collapsing during use and locks in the folded position to keep it out of the way. The rear aperture is adjustable for windage via the tool-less adjustment knob and features two aperture types depending on your preference. The low-profile sight base attaches to 1913 picatinny rails. Ensure your AR-15 or AR-10 will keep you in the fight with these back-up rear and front iron sights.

➲ 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.

➲ 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 shooters night vision by disrupting the muzzle flash when firing in low light 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.
