Holosun SCS-VP9-GR Red Dot Sight Green Multi-Reticle Illuminated Black for H&K VP9

The SCS-VP9-GR (Solar Charging Sight) is designed for the H&K VP9 optics ready handguns. It is designed to attach directly to the slide without an adapter plate and uses a solar charging system with multidirectional light sensors to automatically adjust brightness. The SCS can potentially operate indefinitely using an internal, rechargeable 20,000-hour battery meaning you will never need to change batteries again. Included is an intensity override function which locks the optic into a high brightness mode for 30 minutes.
