The SureFire Scout Light Pro Weaponlight delivers 1000 lumens and can be mounted on a Picatinny or M-LOK rail and swivels as needed—toward the rifle for a slimmer profile with less likelihood of snagging on brush, or away from it to make room for other accessories. The Scout Light Pro's Total Internal Reflection lens allows for a bright beam with long throw and ample surrounding light. The light is controlled on a momentary or constant-on basis with a push-button tail cap switch, shrouded to guard against accidental activation. Its hard-anodized aluminum housing is O-ring sealed against the elements. Power is supplied by two CR123A batteries with 1.3 hours of runtime.
