Product Overview
ARO-GR2 – Compact 2 MOA Green Dot Optic with Shake Awake™
The ARO-GR2 represents the next generation of compact rifle optics, building upon the success of Holosun’s 403 and 503 series. With a refined 22mm housing and green 2 MOA dot reticle, this optic delivers precision, reliability, and a lightweight footprint ideal for duty, home defense, or competition use.
Engineered for modern shooters, the ARO-GR2 features Shake Awake™ Technology to conserve battery life by powering down the LED during inactivity—reactivating instantly at the slightest motion. A single CR2032 battery powers the optic for up to 50,000 hours of continuous runtime. You also get 10 daylight and 2 night vision brightness settings, making the ARO adaptable to any lighting condition.
Its multi-coated glass ensures a crisp, distortion-free sight picture, and its 1.63” lower 1/3 co-witness pedestal mount is perfect for pairing with backup iron sights or magnifiers. For low-profile applications, a 1.05” low mount is also included.
