Fenix Flashlight has engineered the GL06 Rechargeable Tactical Weaponlight to enhance visibility and targeting capability in shooting activities. Specifically designed for compact pistols, this gun light will work with select pistols that have barrel lengths measuring 4". It does accommodate 3" sub-compact models. The GL06 delivers intense white light at 400 or 600 lumens and attaches quickly and securely to both Glock universal and Picatinny accessory rails with a patented quick detach lever. The ambidextrous rear switches provide instant one-finger control of momentary-on or constant-on activation. The strobe mode can be activated by long-pressing with the light on to help you control the situation.
