The KM1-E bezel assembly provides both white light and infrared illumination from a single 123A battery when used on an M300 Scout Light(R). This small, rugged WeaponLight features SureFire's proprietary TIR lens, a far-reaching, high-intensity beam with ample surround light. Simply select the appropriate spectrum for the mission by rotating the bezel. Constructed of lightweight aerospace aluminum coated with a Mil-Spec hard-anodized finish, the ultra-compact KM1-E will withstand the rigors of combat without weighing down your weapon. Upgrade your legacy M300A, B or C Mini Scout Light(R) to 250 lumens plus 100 mW of infrared illumination with the KM1-E bezel.
