The SureFire 623LM LED WeaponLight (2 Switches) replaces the Mossberg 590 or 500 original forend. This compact weapon light features a 6.0V/2 battery system and a virtually indestructible LED lamp with a TIR lens. The front-end is molded from a tough polymer with an integral high-friction surface for an enhanced grip. The illumination system is configured with two separate switches; a momentary-on pressure-pad on the right side and a constant-on rocker switch on the left side. When activated, the LED WeaponLight pumps out a blazing 200 lumen beam of brilliant white light.
