The M300 Mini Scout is mighty in stature yet minimal in structure. It 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, and it easily and securely attaches to MIL-STD-1913 Picatinny rails via its integral M75 thumbscrew mount. Activation is easy: Simply click its push-button tailcap switch or press 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 withstands the rigors of combat without weighing down your weapon.
