Featuring two levels of tactical illumination, ambidextrous switching, a slender ergonomic design, and legendary SureFire reliability and durability, the DSF-500/590 is the ultimate WeaponLight for Mossberg 500 or 590 shotguns. This compact, lightweight system replaces the weapon’s original factory forend and features a recoil-proof LED that generates 600 lumens of blinding white light at maximum output, or 200 lumens with twice the runtime on its high setting. The LED’s light is focused by a precision reflector to create a smooth, wide beam perfect for closer-range shotgun applications typical in law enforcement and home defense—with enough reach and surround light to properly identify threats and maintain situational awareness. Large, tactile momentary and constant-on switches on both sides provide precise control by left- and right-handed shooters.
