The M300 Mini Scout is a powerful, lightweight weapon-mounted light-powered by a single 123A lithium battery-that features a virtually indestructible LED, which generates 500 lumens of light focused by a TIR lens into a high-intensity beam with plenty of reach for close- to mid-range operations. The rugged M300 easily and securely attaches to MIL-STD-1913 Picatinny rails via its integral thumbscrew clamp and is activated by clicking its pushbutton tail cap switch or pressing its pressure-activated tape switch, included on appropriate models. Machined from lightweight aerospace aluminum with a Mil-Spec hard anodized finish and O-ring sealed to keep out the elements, the ultra-compact M300 will withstand the rigors of combat without weighing down your weapon.
