Drop Darkness In its Tracks. The M603V Scout Light® is the right tool for the toughest missions. Focused by a TIR lens, its versatile 350-lumen hybrid beam can overwhelm an aggressor’s dark-adapted vision while providing plenty of throw for positive target identification and ample spill light to help you maintain situational awareness. Its IR mode produces a 120-milliwatt beam invisible to the naked eye, ideal for NVG missions. Switching between the two light spectra is intuitive and easy, even on the fly. Rugged and reliable, the M603V securely attaches to MIL-STD-1913 Picatinny rails via its integral M75 thumbscrew clamp. To activate, press its push-button tailcap switch or, for precise fingertip control without altering your grip, press its pressure-activated tape switch (both are included). Our SR07-D-IT dual remote switch simultaneously controls the activation of the M603V and an ATPIAL or DBAL laser. Like all SureFire products, the M603V is built to win the fight.
