Sons of Liberty Gun Works M89 Free-Float Drive Lock M-LOK Rail 8", Black - Compact and Versatile Rail System - M89-8

The revolutionary Drivelock design, developed in collaboration with Icon Defense, utilizes three independent wedges that engage with angular grooves machined into their proprietary barrel nut. This innovative system ensures a secure and precise clamping of the rail onto the steel barrel nut, delivering exceptional force and precision. In addition to securing the rail, the Drivelock system applies force that pushes the handguard rearward towards the upper receiver. This dual-action feature not only enhances the overall stability and alignment of the firearm but also reinforces the structural integrity of the assembly. Furthermore, the slightly larger inner diameter of the extrusion around the gas block provides additional space, which promotes improved airflow and heat dissipation. This design element contributes to enhanced rigidity compared to traditional systems like the M76, ensuring optimal performance and durability over extended use. Overall, the Drivelock system represents a significant advancement in firearm accessory technology, offering robust construction, precise functionality, and superior heat management. It is engineered to meet the rigorous demands of professional users and enthusiasts alike, providing reliability and performance in diverse operational scenarios.
