Holosun ARO Green Dot Sight with Multiple Reticle System and Lower 1/3 Co-Witness Mount

Advanced Rifle Optic Performance: Holosun ARO Green Dot

The Holosun ARO Green Dot Sight delivers fast target acquisition, rugged durability, and advanced reticle versatility in a compact rifle optic package. Designed as an upgrade to Holosun’s popular 403 and 503 series optics, the ARO features a larger 22mm housing, a crisp green Multiple Reticle System (MRS), and a durable mounting solution optimized for modern sporting rifles and defensive carbines.

Multiple Reticle System (MRS)

The ARO features Holosun’s proven Multiple Reticle System, allowing shooters to choose between a precise 2 MOA dot, a fast-acquisition 65 MOA circle, or a combined 2 MOA dot with 65 MOA circle. The green reticle provides excellent visibility in varying lighting conditions while promoting rapid sight alignment.

Optimized 22mm Housing Design

Built around a redesigned 22mm optic housing, the ARO pairs perfectly with Holosun magnifiers while offering a wider field of view and improved optic integration. The included 1.63" lower 1/3 co-witness mount provides an ideal sight height for AR-platform rifles and modern shooting setups.

Shake Awake Technology

Holosun’s Shake Awake technology automatically activates the optic when movement is detected and powers it down during inactivity to preserve battery life. Powered by a single CR2032 battery, the ARO delivers dependable long-term performance.

Built for Daylight and Night Vision Use

With 10 daylight brightness settings and 2 night vision compatible settings, the ARO adapts easily to a wide range of shooting environments. The rugged black housing is engineered for reliable use in demanding conditions.
