6mm ARC was engineered by Hornady to deliver long-range ballistic performance from a standard AR-15 bolt and magazine envelope, stabilizing heavy, high-BC projectiles for precision reach beyond what 5.56 offers. The L89A's integrated ARCA rail lets you mount straight to a tripod without an adapter, and together with the Drivelock barrel nut, internal dowel pin, and anti-rotation tabs, it minimizes the micro-movement that shifts point of impact when a laser module or VAS is rail-mounted. The bare-threaded muzzle leaves you free to install a suppressor mount, brake, or flash hider without removing a pre-installed device.

Sons of Liberty Gun Works builds and test-fires every rifle and barreled upper in the United States, applying the same standards to individual components as they do to their complete rifles.
