Holosun® ARO RD2 Red Dot Sight

The Holosun^® ARO RD2 Red Dot Sight is a compact, precise, and durable next-generation optic that elevates any rifle. With its modern design, 22 mm objective lens, crisp 2 MOA red dot, and ShakeAwake™ technology, the ARO RD2 is an ideal choice for shooters seeking reliability, performance, and a distortion-free image.

Optimized for Modern Rifles

Developed in response to the needs of today’s shooters, the ARO RD2 builds on the proven 403/503 series with an improved housing, refined mount design, and a larger 22 mm lens. The result is a wider field of view, faster target acquisition, and seamless compatibility with magnifier modules.

Seamless Compatibility

The ARO RD2 uses the industry-standard T2 footprint, ensuring compatibility with mounts from other manufacturers. A high mount with lower 1/3 co-witness is included, making it perfectly suited for use with flip-up sights. Installation is quick, stable, and hassle-free.

Endurance You Can Rely On

Powered by a CR2032 battery, the ARO RD2 provides up to 50,000 hours of runtime. ShakeAwake™ technology automatically powers the optic down when not in use and instantly reactivates it with movement—ensuring the sight is always ready while conserving battery life.
