This powerful and versatile XH30 Weapon Light was created to interface with SureFire's revolutionary MASTERFIRE Rapid Deploy Holster. It features a unique bezel with cam slots, and pin slots on both sides of the body, which serve to lock the light into the holster and secure the weapon at an advantageous angle for quick deployment. As a tactical weapon-mounted light, the XH30 is remarkable on its own. It features a recoil-proof LED paired with a Total Internal Reflection (TIR) lens which creates a far-reaching, high-intensity beam with ample surrounding light. Constructed of lightweight but strong aerospace-aluminum body with a Mil-Spec hard anodized finish for superior toughness - and then O-ring and gasket sealed for weatherproofing - this tough-as-nails Weapon Light never needs to be babied. The XH30 includes two mode selector switches. One for toggling between 1000 blinding lumens of light to gain a superior advantage in the dark and 300 potent lumens when less light is needed. The second switch toggles between continuous light operation and a disorienting strobe mode. Activating the XH30 is achieved via one-finger, ambidextrous switching located at the rear of body. Optional DG grip switches (for pistols), which allow for surgical activation without altering your grip on the weapon at all, are also available. And the versatile XH30 can be easily and securely attached to any pistol or long gun equipped with a Universal or Picatinny rail via its Rail-Lock system.Features:Total internal reflection (TIR) lensAmbidextrous switchesAccepts optional DG switches
