The SCS-P10-GR (Solar Charging Sight) is designed for the CZ-P10 optics-ready handguns. It is designed to attach directly to the slide without an adapter plate and uses our innovative solar charging system with multi-directional light sensors to automatically adjust brightness in dynamic situations. The SCS can potentially operate indefinitely with its internal, rechargeable 20,000-hour battery. With moderate exposure to bright light the SCS models charge the battery with more power used to display the reticle so you will never need to change batteries again.
