SureFire X300U-B Tactical Weaponlight LED
The SureFire X300U-B delivers an intense 1,000-lumen output optimized for human vision with an off-white LED beam. Engineered with a precision Total Internal Reflection (TIR) lens, it creates a far-reaching, high-candela central beam with generous peripheral illumination to maintain critical situational awareness.
Built for extreme tactical conditions, this weaponlight features high-strength aerospace aluminum construction finished with Mil-Spec hard anodizing and a tempered coated window. The integrated aluminum T-slot mounting system provides a rugged, secure attachment to railed handguns and long guns equipped with MIL-STD 1913 rails.
