➲ M-LOK Handguard
New for 2022, these AR-15 handguards are built to provide rugged, reliable performance. 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.
➲ 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 shooter?s 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.
➲ 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. This provides not only an impressive barrel life but ensures excellent accuracy. The barrel threads are carefully threaded to the .308 standard. Optimized for stability with a 1:7 twist rate, this 300 BLK barrel can handle heavier bullets used for subsonic loads with ease.
➲ 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.
