Sons of Liberty Gun Works M89 Free-Float Drive Lock M-LOK Rail 16.75", Black - Extra-Length Rail for Custom Build - M89-16.75

The revolutionary Drivelock design, developed in collaboration with Icon Defense, introduces a patent-pending system featuring three independent wedges that engage with angular grooves integrated into their proprietary barrel nut. This innovative mechanism ensures a secure and precise clamping of the rail onto the steel barrel nut, delivering exceptional force and precision. Beyond its clamping capability, the Drivelock system also exerts force that pushes the handguard rearward towards the upper receiver. This dual-action functionality not only enhances the structural integrity of the firearm assembly but also optimizes alignment and stability during operation. The handguard's slightly larger inner diameter provides additional space around the gas block, facilitating improved airflow and heat dissipation. This design characteristic not only enhances rigidity, surpassing traditional systems like the M76, but also ensures prolonged performance and reliability under demanding conditions. The Drivelock system represents a significant advancement in firearm accessory technology, offering robust construction and advanced functionality. Engineered to meet the stringent requirements of professionals and enthusiasts, it provides unparalleled durability, precision, and heat management, making it an ideal choice for high-performance applications.
