Providing 350 lumens of bright white light and infrared output compatible with night-vision devices, the X300V Handgun and Long Gun WeaponLight by Surefire provides the illumination you need for tactical use. Easily mounted to most handguns or long guns with the quick attach/detach Rail-Lock system, the X300V employs a Total Internal Reflection (TIR) lens to shape white or IR light into focused beams with enough reach and surrounding light for close to medium-range applications. The on-off toggle switch is support-hand-accessible for left and right-handed shooters; press for momentary-on, push up or down for constant-on. Switching from white to IR light is accomplished by turning the head, and there's an off position there, too.

The light is compatible with any universal or Picatinny mounting rail. Optional adapter mounts for several non-railed handguns are available from SureFire. O-ring and gasket seals keep moisture out, and the light's hard-anodised aluminium housing resists the wear and tear of regular use. It measures 4 x 1" and weighs 3.9 oz with the included SureFire SF123A lithium batteries.
