The Mini Scout Light Pro is a small and mighty weapon light featuring SureFire's new Low-Profile Mount (LPM). It delivers unprecedented versatility by allowing the user to optimize the light's position relative to the rail and the LPM securely attaches to any MIL-STD-1913 or M-LOK rail.This light feeds off a single 123A lithium battery, but its virtually indestructible LED devours darkness with 500 lumens of light focused by a TIR lens into a high-intensity beam. It's ideal for close- to longer-range operations. To activate the light simply click the push-button tailcap switch or press its pressure-activated tape switch (sold separately).
