ATS Tactical Gear is featuring this Surefire X300... "The versatile SureFire X300™ features a solid-state, electronically regulated LED that generates 110 lumens of tactical-level light — enough to overwhelm an aggressor's night-adapted vision. Its specially developed Total Internal Reflection (TIR) lens creates a bright, tightly focused central beam with plenty of reach and enough surround beam to accommodate peripheral vision.

A hard-anodized aerospace-grade aluminum body protects the X300's electronics, and O-ring seals and gaskets make the entire unit waterproof to 22 meters. A tempered Pyrex® window protects its LED and, thanks to a thin layer of anti-reflective coating, helps maximize light transmission.

The X300 attaches to both Universal and Picatinny rails in moments, via its proprietary Rail-Lock™ system, and comes with adapter plates for both. An ambidextrous toggle/push switch provides convenient, fail-safe operation. Optional SureFire grip switches, which allow precision control without altering one's grip on the weapon, are also available for many handguns.
