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.
➲ 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 phosphate 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.

Designed with the advanced shooter in mind, these handguards are light and ergonomic, features that provide faster on-target performance and reduced fatigue. Includes robust steel mounting hardware to ensure an easy installation and a rock solid platform.
➲ Straight 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 416-R Stainless 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.
➲ 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.
