SureFire's M600P Fury Scout Light gives you 600 lumens of blinding white LED-generated light at the press of a fingertip. Like our top-selling Fury flashlights, the M600P provides a wider reflector-shaped beam with increased surround light, as opposed to the higher-intensity, farther-reaching beam created by the TIR lenses found on most Scout Lights. It attaches by means of an integral thumbscrew clamp to long guns equipped with a Picatinny rail. The M600P comes with two switches: a pushbutton tailcap switch: press for momentary on, press further to click constant-on; and a momentary-on tape switch with a 7-inch cable that attaches to your preferred location via self-stick Velcro backing. It attaches by means of an integral thumbscrew clamp to long guns equipped with a Picatinny rail.
