With its low profile this gas block allows it to fit under the most ergonomically designed handguards and rails on the market.
➲ Pistol Length Gas Tube
An essential component to your AR15 is the gas tube, which keeps your build up and running. This gas pistol-length tube is constructed from corrosion resistant stainless steel ensuring a lifetime of service.
➲ 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.
➲ Bolt Carrier Group
There is nothing more crucial to the performance of your AR-15 than the bolt carrier group. Manufactured to MIL-SPEC and finished with a superior quality nitride finish that protects against corrosion and heat, our BCG will not let you down. To ensure that it will provide superior performance in your AR-15, each bolt carrier group undergoes high-pressure testing (HPT) and magnetic particle inspection (MPI). Whether you’re looking for a drop-in Mil-Spec quality replacement for your current AR, or are going for a new build, this bolt carrier group provides you with the reliability and performance you expect from a premium product.
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 1:8 twist rate, this 300 BLK barrel can handle heavier bullets used for subsonic loads with ease.
➲ Standard MIL-SPEC Charging Handle
A central component of your AR-15, the charging handle not only assists in chambering a round, but is your main tool to clear a round that won’t eject cleanly. The 7075-T6 aluminum design results in a rugged and capable charging handle for your AR-15. With lightweight aluminum construction and a traditional snag-free latch design, this charging handle provides superior function and reliability.
