It runs on rechargeable litium polymer batteries (included), and has a TIR optic lens to provide a 245-meter focused beam that is still wide enough to eliminate blind spots in the dark. The quick attach and release mounting system allows easy and secure attachment to any firearm with a 1913 or Glock style rail. Features: Ambidextrous switch that can be front pushed or side pressed. Compact to fit all standard pistol sizes.
