Holosun® ARO MRS RD Red Dot Sight

The Holosun^® ARO MRS RD Red Dot Sight delivers a crisp image, instant activation, and a versatile reticle that adapts to any shooting style or environment. With a 22 mm optical window, modern construction, and intuitive controls, it represents the next generation of optics—fast, reliable, and uncompromising.

Wider tube, greater view

Building on the proven HS403/HS503 series, the ARO MRS RD adds what shooters have been waiting for. The 22 mm objective aligns seamlessly with magnifier modules, while the redesigned housing and mount maximize visibility with minimal obstruction.

Multiple Reticle System (MRS)

The optic offers a switchable reticle: a fine 2 MOA dot, a 65 MOA circle, or a combination of both. Select the setup that best matches your mission—precise shots at distance or rapid CQB engagement. The sight also remembers your last setting after shutdown.

Automation meets durability

Holosun’s ShakeAwake™ technology conserves battery life by powering down the sight when idle and instantly reactivating it with movement. The robust aluminum housing and aspherical glass ensure a distortion-free, stable image even in demanding conditions.

Ready for any platform

The optic is parallax-free with unlimited eye relief, making it suitable for a wide range of rifles. It uses the industry-standard T2 footprint for maximum mount compatibility and comes with a high (lower 1/3 co-witness) mount included.
