Sons of Liberty Gun Works M89 Drive Lock Rail M-LOK 11.5in Includes Steel QD Socket Black

The Drivelock 11.5" MLOK Rail, developed in collaboration with Icon Defense, brings a new level of handguard lockup and rigidity to modern sporting rifles. Its patentpending Drivelock design uses three independent wedges that engage angular grooves in the supplied proprietary steel barrel nut. As the wedges tighten, they clamp the rail to the barrel nut with extreme force and precision while simultaneously driving the handguard rearward toward the upper receiver - locking your rail and sight plane into a repeatable, robust platform.Built from lightweight aircraftgrade aluminum and finished in durable hardanodized black, the Drivelock rail offers a Tmarked flat top for consistent optic placement and multiple MLOK slots for accessory modularity. The slightly larger inside diameter gives you more real estate around the gas block and helps the extrusion run cooler under sustained use. Each rail ships with the barrel nut, barrel wrench, lockup components, and all installation hardware so you have everything needed for a proper installation.
