The Holosun ARO-RG2 Gold Dot Sight is purpose-built for shooters who demand fast, reliable target acquisition in a compact and rugged package—without compromising on clarity, durability, or battery life. Evolving from the trusted 20mm HS403/503 platform, this next-gen Advanced Rifle Optic features an expanded 22mm window, perfectly compatible with Holosun’s HM3X/HM3XT magnifiers. It ships with both a 1.63" lower 1/3 co-witness mount and a 1.05" low-profile mount, ensuring seamless fitment across ARs, PCCs, shotguns, and offset pistol configurations.
Housed in lightweight, hard-anodized aluminum, the ARO-RD2 showcases a crisp 2 MOA gold dot projected by an ultra-efficient LED system with up to 50,000 hours of runtime on a single CR2032 battery. With 10 daylight brightness levels and 2 night vision settings, the optic delivers true 1x magnification, unlimited eye relief, and parallax-free performance, making it ideal for rapid engagements from close quarters to mid-range.
Compact at just 2.48" x 1.54" x 2.63" and weighing only 3.38 oz, the ARO-GD2 stays out of the way until you're ready—then activates instantly via Shake Awake™ technology. Multi-coated glass resists glare and abrasion, while included tools and a microfiber cloth make installation and maintenance hassle-free.
For shooters who prefer a gold dot over traditional red, the Holosun ARO-GD2 delivers best-in-class performance, flexible mounting options, and field-proven reliability—all in a micro-sized footprint ready for any mission.
