➲ .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 steel with a smooth phosphate finish, this .936 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.
➲ Rifle Length Gas Tube
An essential component to your AR15 is the gas tube, which keeps your build up and running. This rifle-length gas tube is constructed from corrosion resistant stainless steel ensuring a lifetime of service.
➲ Spiral Fluted Barrel
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. This is the perfect barrel for an AR build, keeping weight to an absolute minimum due to the fluting, while still offering a significant ballistic advantage.
