The Sons Of Liberty Gun Works M89H11.5 Drive Lock Rail is an 11.5-inch handguard for AR-15 platforms, engineered for strength and accessory mounting flexibility. Its patent-pending Drive Lock system uses three wedges to clamp the rail to a proprietary steel barrel nut, enhancing rigidity and providing extra internal clearance for larger low-profile gas blocks. The hard-anodized black aluminum construction delivers lightweight durability, with M-LOK slots and engraved T-marks for accessory placement.
The M89H11.5 offers a rigid, durable design with broad accessory mounting options. All installation hardware, including barrel nut and lock-up components, is included for straightforward setup.
