SureFire X300V-B Weaponlight, 350 Lumens, White & IR

The SureFire X300V-B is a dual-spectrum weapon-mounted light that integrates both white-light and infrared output in a sealed, recoil-resistant head. It provides white illumination for routine low-light visibility and an infrared beam for use with night-vision devices. The unit mounts to most handguns and railed long guns using a T-slot/Rail-Lock system and is designed for durable, weather-resistant service.
