Product description
The Holosun ARO GR2 is a compact and durable green dot sight featuring a precise 2 MOA reticle designed for rapid target acquisition. This sight incorporates Holosun’s Shake Awake technology, which automatically powers the unit on when motion is detected and conserves battery life by turning off when stationary.
Constructed from robust aluminum with a hard anodized finish, the ARO GR2 is waterproof and shock-resistant, making it suitable for tactical, hunting, and competitive shooting applications. It offers multiple brightness settings with automatic adjustment to optimize visibility across different lighting conditions.
