Holosun® ARO MRS GR Red Dot Sight

The Holosun^® ARO MRS GR Red Dot Sight delivers fast target acquisition and dependable performance in a compact, durable package. Its Multiple Reticle System (MRS) lets you choose a 2 MOA dot, a 65 MOA circle, or both—so you can tailor the sight picture to the mission.

Clear, flexible aiming

The 22 mm optical window provides an expansive view and crisp reticle definition. Select the green 2 MOA dot for precision, the 65 MOA circle for rapid CQB indexing, or run the combined reticle for maximum versatility. Parallax‑free with unlimited eye relief.

Controls that keep up

12 brightness settings (including night‑vision‑compatible levels) ensure visibility in any light. Holosun’s ShakeAwake™ wakes the optic on movement and preserves power when idle, with up to 50,000 hours of runtime from a CR2032 battery.

Built for hard use

A robust aluminum housing and quality coatings stand up to impact and weather. The ARO MRS GR uses the industry‑standard T2 footprint for broad mount compatibility, and ships with a lower 1/3 co‑witness mount for immediate setup.
