Holosun SCRS-GR MRS 20mm Solar Charging Rifle Green Dot Sight

Holosun SCRS-GR MRS 20mm Solar Charging Rifle Sight is a compact, tube-style rifle optic designed to deliver a non-magnified green aiming solution for long-gun platforms. Built by Holosun, this sight combines a 20 mm tube format with a selectable multi-reticle system and solar-assisted rechargeable power for consistent performance across a wide range of lighting conditions.

The SCRS-GR MRS is intended for rifle users who want a durable, low-profile optic with flexible reticle options and minimal maintenance. Its tube-style design offers a familiar sight picture while remaining compact enough for primary or offset mounting. Solar charging paired with an internal rechargeable battery reduces the need for frequent battery changes, making the optic well suited for patrol, training, and range rifles where reliability and simplicity are priorities.

Specifications & Build

The SCRS-GR MRS is constructed from 7075 aluminum for strength and reduced weight, finished in black anodizing for corrosion resistance. It operates at 1× magnification and uses a 20 mm tube with multi-coated lenses to support a clear sight picture. The reticle system provides a 2 MOA dot and a 65 MOA circle in green illumination. Power is supplied by an internal rechargeable battery supplemented by solar charging, with some descriptions noting extended runtime up to approximately 50,000 hours depending on settings. Windage and elevation adjustments are adjustable in 1 MOA increments, and the optic is listed as waterproof.

Compatibility & Intended Use

Designed for rifle and other long-gun platforms, the SCRS-GR MRS uses the Holosun 509T mounting footprint and is compatible with third-party offset RDS mounts. It can be configured as a primary non-magnified optic or as an offset sight, and variant mounting options support lower 1/3 co-witness or approximately 1.63-inch height setups depending on mount selection. Typical applications include patrol rifles, training and range rifles, and general-purpose long-gun configurations.
