The Holosun ARO Advanced Rifle Optic with Multi Reticle System (MRS) offers precision, durability, and versatility in a compact design. Featuring a 22mm housing, 2 MOA dot with 65 MOA circle, and Shake Awakeâ„¢ Technology for extended 50,000-hour battery life, it's built for rapid target acquisition and seamless readiness. The Super LED delivers 12 brightness settings, including night vision compatibility, while the durable aluminium housing ensures performance in harsh environments with IP67 waterproofing and shock resistance up to 1000G.
The Holosun ARO Advanced Rifle Optic with Multi Reticle System (MRS) represents the next generation in precision shooting technology. Building on the legacy of the popular 20mm 403 and 503 series, the ARO introduces a redesigned 22mm housing that integrates seamlessly with Holosun’s magnifier range and features an all-new 1.63" lower 1/3 co-witness pedestal mount, delivering superior alignment and target acquisition.
At the heart of the ARO lies Holosun’s Multi-Reticle System (MRS), allowing users to effortlessly toggle between a 2 MOA dot, a 65 MOA circle, or a combination of both. This flexibility ensures fast target engagement at close quarters, while also providing a clean, precise aiming point for longer-range shots. Whether you're on the range or in the field, the MRS adapts to your needs for ultimate versatility.
The optic is equipped with Shake Awakeâ„¢ Technology, a motion-sensitive feature that conserves battery life by deactivating the LED when idle and reactivating it instantly upon movement. This ensures your optic is always ready when you are, with user-configurable sleep timers ranging from 10 minutes to 12 hours. Paired with a CR2032 battery, the ARO offers an astonishing battery life of up to 50,000 hours, delivering unmatched reliability.
Holosun’s Super LED technology supports 10 daylight and 2 night vision brightness settings, providing crystal-clear visuals in any lighting condition. The lens is treated with multi-layer reflective coatings to enhance clarity and reduce glare, all housed in a durable aluminium body finished in MAO for maximum resilience. The optic is also parallax-free, offers unlimited eye relief, and is IP67-rated waterproof, making it a dependable companion in the harshest environments.
Compact yet rugged, the ARO weighs just 3.38oz and measures 2.48 x 1.54 x 2.63 inches, with ±50 MOA windage and elevation adjustment range and 0.5 MOA per click precision. Built to withstand temperatures from -30°C to 60°C in use and storage from -40°C to 70°C, it’s also shockproof to 1000G, ready for whatever comes its way.
