The Sons Of Liberty Gun Works M89H13 Heavy Drive Lock M-LOK Handguard is a 13-inch rail engineered for AR-15 platforms, prioritizing a secure fit and accessory flexibility. Its innovative patent-pending Drivelock system uses three independent wedges to clamp the handguard to a proprietary barrel nut, developed in collaboration with Icon Defense, resulting in enhanced rigidity and improved alignment. Manufactured from aircraft aluminum with a MIL-A-8625F Type III Class 2 hard anodized finish, this handguard features a slightly larger inner diameter for better gas block clearance and heat management.
The M89H13 is designed for users seeking reliable stability and versatile accessory mounting on AR-15 builds. Its thoughtful construction and feature set support both high performance and customization needs.
