I was too afraid to try it on myself and there’s a minimum stand-off distance required to use it or it can cause permanent blindness. But yes, this is an actual non-lethal weapon we employed as part of stability operations (STABOPS) in Afghanistan. It overwhelms the eye in some way and causes temporary blindness from several hundred yards away. We mounted our ‘dazzlers’ on rifle vertical grips and tri-rail picatinny rail mount systems and them placed an EOTech sight on top. The total rig cam in under 3 lbs. and was effective during the day or the night.
