The M6X Tactical Laser Illuminator was built for U.S. Special Operations personnel and designed to perform under the most rigorous conditions and survive the harshest environments. Because of this, the M6X is built to go as deep as 66ft. and still remain waterproof. Now equipped with a high-performance LED that delivers a peak output of 150+ lumens, the M6X LED is built to these same tough standards. Powered by two (2) 3V 123 lithium batteries (included), the M6X LED has a run time of two (2) hours. The M6X LED utilizes a red, class III visible laser with a range of 200 meters. The laser is adjustable for elevation and wind age (using the supplied tool) allowing the user to zero in the laser.
