Holosun SCRS MRS

The Holosun SCRS (Solar Charging Rifle Sight) MRS is the lightest rifle red dot Holosun makes, with a 20mm tube housing that weighs just 2.5 oz before the mount. The defining feature is the integrated solar panel paired with an internal rechargeable battery, eliminating the CR2032 entirely. The optic charges from ambient light during use and stores power in the internal cell for low-light operation, delivering up to 20,000 hours of runtime at brightness setting 6 with no battery to swap.

The Multi-Reticle System provides a 2 MOA dot for precision, a 65 MOA circle for speed, or both combined. Auto Mode reads ambient light through the forward-facing sensor and adjusts reticle intensity automatically, with Manual Mode offering 8 daylight and 4 night-vision compatible settings for shooters who prefer direct control. Shake Awake powers the optic instantly on motion and shuts down when idle to maximize runtime.

The 509T footprint is the standout feature for builders. The SCRS bolts onto the same mounts as the Holosun 509T, including offset 45° mounts, piggyback magnifier scope mounts, and quick-detach options across the aftermarket. The included 1.63" riser provides lower 1/3 co-witness on standard AR setups. Construction is 7075-T6 aluminum with MAO finish, IP67 water and dust resistance, and 1000G vibration resistance. At ~$318, the SCRS MRS is the most travel-friendly red dot in the Holosun catalog and the only one with a battery you never replace.
