Sons of Liberty Gun Works L89 Drive Lock Rail Features The Sons of Liberty Gun Works L89 Drive Lock Rail builds on the proven M89 Drivelock lockup system while incorporating end user feedback to maximize utility in modern combative applications. Seven sided M-LOK attachment slots run the length of the handguard giving the shooter mounting options at nearly every angle for lights grips and other accessories. Two integrated steel QD sockets are built directly into the rail providing fast secure sling attachment points without the need for separate QD mounts. Fast slots positioned beneath the 12 o clock position allow zip ties to route cables cleanly along the top of the handguard. At 13.75 inches long and 16.7 ounces installed this handguard balances coverage with weight savings an important tradeoff for a fighting rifle that needs to stay fast on target. The included steel barrel nut locks the handguard to the receiver with maximum strength supporting the rail under hard use and repeated accessory changes. Its anodized black finish resists wear and corrosion while matching standard AR-15 finishes. For shooters upgrading an existing build or finishing a custom rifle the L89 Drive Lock Rail is a durable combat proven handguard option.
