The L89 Drivelock handguard utilizes a titanium barrel nut and a three-point locking system to ensure that rail-mounted optics and lasers maintain a rock-solid zero. This "No Muzzle Device" (NMD) version provides a bare 1/2x28 threaded muzzle, allowing the end-user to install their specific suppressor mount or flash hider of choice.
