Surefire M300V IR Scout Weapon Light



The ultra-compact M300V Scout Light, powered by one 123A lithium battery, produces 250 lumens of brilliant white light or 100 mW of invisible infrared illumination for use with night vision devices — with no need for IR filters or spare lamps. The M300V's TIR lens produces a tight beam suited for close- to medium-range applications. The high-efficiency LEDs are virtually immune to failure since there's no filament to burn out or break. 

The ultra-compact weapon light clamps to any rifle equipped with a Picatinny rail via its integral M75 thumbscrew mount. Constructed of high-strength aerospace aluminum with Mil-Spec hard anodizing for superior toughness and corrosion resistance.
