The Holosun SCRS-RD-2 is a compact, solar-powered 20mm tube red dot sight designed specifically for rifles and carbines. Built around Holosun’s Solar Charging Rifle Sight (SCRS) technology, it combines an ultra-efficient internal rechargeable battery with multi-directional light sensors that automatically adjust reticle brightness based on ambient lighting conditions.
This optic offers both automatic and manual brightness modes, allowing users to fine-tune performance for varying environments. Constructed from durable 7075-T6 aluminum, the SCRS-RD-2 is built for hard use while maintaining a lightweight, low-profile footprint. It includes a lower 1/3 co-witness 1.63" mount and utilizes Holosun’s 509T footprint for compatibility with offset mounting systems.
With up to 50,000 hours of runtime, night vision compatibility, and a simple 2 MOA red dot reticle, the SCRS-RD-2 delivers reliable performance for duty, defensive, or range applications.
