Sons Of Liberty Gun Works 15" M89Heavy Drive M-Lok Rail with Steel QD Sockets

The revolutionary, patent-pending Drivelock design—developed in collaboration with Icon Defense—features three independent wedges that engage with angular grooves in a proprietary steel barrel nut. This innovative lock-up system clamps the rail onto the nut with extreme force while simultaneously driving the handguard rearward, ensuring a tight and durable fit. The larger internal diameter provides more clearance around the gas block and improved rigidity compared to the M76 handguard, while also enhancing heat resistance. The handguard is finished in a non-reflective, hard-anodized coating matched to SOLGW receivers and features engraved T-marks for consistent mounting.

Includes: Rail, Barrel Nut, Barrel Nut Wrench, and Lock-Up Components.
