The Holosun ARO (Advanced Rifle Optic) is the next evolution of the popular 403 and 503 series optics, built to deliver precision, speed, and rugged reliability. Featuring a larger 22 mm housing for improved field of view, it integrates perfectly with Holosun magnifiers and ships with both a 1.63 lower 1/3 co-witness mount and a 1.05 low mount. Equipped with Holosun's Multi-Reticle System (MRS), you can switch between a precise 2 MOA dot or a 65 MOA circle-dot for faster target acquisition at close range. Built with Shake Awake technology, multilayer reflective glass, and IP67-rated housing, the ARO is ready for duty, defence, or competition in any environment.
