The SureFire DSF-M1/M2 is designed to replace the factory forend of the Benelli M1/M2 shotgun. It features an ultra-high-output, recoil-proof LED that generates 600 blinding lumens of white light on its maximum setting and 200 lumens of tactical light with nearly twice the runtime on its high setting. A precision reflector focuses the LED"s light into a smooth, intense beam with ample reach and plenty of peripheral illumination for close- to medium-range applications. The slender, lightweight polymer forend is textured for a positive hold and features an ergonomic output-mode-selector switch, ambidextrous momentary- and constant-on switching and a system-disable switch to prevent accidental activation. Setting the LED"s output level is simply a matter of activating the light in constant-on mode and then pressing the selector switch until the desired output (600 or 200 lumens) is set-the set output level can then be left in constant-on mode or switched to momentary-on. Providing unmatched versatility, durability, illumination and control, the DSF-M1/M2 is the ultimate Weapon Light for Benelli M1/M2 combat shotguns.
