The SCRS-RD (Solar Charging Rifle Sight) represents an advancement in Holosuns SCS technology, introducing a brand-new, ultra-compact 20mm tube sight meticulously designed for long gun applications. The SCRS-RD features multi-directional light sensors and offers two distinct operating modes: Auto Mode for automatic reticle intensity adjustments and Manual Mode for precise manual control of dot intensity settings. Constructed from 7075 aluminum, the SCRS-RD incorporates a lower 1/3 co-witness, 1.63 mount specifically designed to accommodate Holosun s well-established 509T footprint. This ensures compatibility with third-party offset RDS mounts. The SCRS-RD is available in two configurations: a 2MOA dot-only version or the Holosun Multi-Reticle System (MRS). It boasts an extensive selection of 12 reticle intensity settings, including four tailored for night vision device compatibility, all powered by an impressively enduring internal rechargeable battery offering unlimited runtime.
