EOTech OGL Green/IR Laser Sight Grey. The OGL Standard Power (restricted to MIL/LE use) is powered by a single CR123 battery providing up to 9 hours of continuous run time. The machined aluminum housing provides extreme durability in a compact package roughly the size of a standard deck of playing cards. The IR illuminator utilizes a high performing Vertical-Cavity Surface-Emitting Laser (VCSEL) diode creating a clean beam and allowing quick adjustments from spot to flood. The ergonomic (patent pending) lever is unique to the OGL and allows professionals to adjust their illumination needs instantly all while maintaining superior situational awareness.
