Holosun ARO Advanced Rifle Optic with 2MOA Reticle - Red Dot
The Holosun ARO Advanced Rifle Optic features a crisp 2 MOA dot, a compact 22mm housing, and a 1.63" lower 1/3 co-witness mount, making it ideal for fast target acquisition and compatibility with magnifiers. It includes Shake Awake™ Technology for up to 50,000 hours of battery life, multi-coated glass, and parallax-free viewing with unlimited eye relief. Housed in durable aluminium, it's lightweight, IP67 waterproof, and built to perform in extreme environments with 10 daylight and 2 night vision settings.
The Holosun ARO Advanced Rifle Optic takes performance and precision to the next level, building upon the proven success of the popular 403 and 503 series. Featuring an all-new 22mm housing design, the ARO is engineered to pair seamlessly with Holosun’s magnifier systems, making it ideal for shooters seeking a compact, modular setup. Its redesigned 1.63” lower 1/3 co-witness pedestal mount ensures a natural alignment with standard height AR-style sights, enhancing both speed and accuracy in target acquisition.
At the heart of the optic is a 2 MOA dot reticle, offering crisp and precise point-of-aim for both short-range engagements and longer shots when used with magnification. The ARO delivers parallax-free performance with unlimited eye relief, and its multi-coated glass ensures optimal clarity and light transmission in all lighting conditions.
Equipped with Holosun’s innovative Shake Awake™ Technology, the ARO intelligently conserves battery life by powering down the LED when no motion is detected, and instantly reactivating it the moment movement is sensed. This feature provides up to 50,000 hours of battery life from a single CR2032 battery, offering reliable performance whether on duty, at the range, or stored for home defence.
Crafted from durable aluminium with a MAO surface finish, the optic is built to withstand the elements. Its compact dimensions and light weight, just 3.38oz, make it a perfect companion for modern sporting rifles. Rated IP67 for water resistance, with operational temperatures ranging from -30°C to 60°C, and tested for 1000G vibration resistance, the ARO is ready for the most demanding conditions.
With 10 daylight and 2 night vision brightness settings, precision 0.5 MOA adjustments, and a rugged, streamlined form factor, the Holosun ARO delivers elite-level performance in a compact, reliable package.
