Performance and optics
The 2 MOA green dot on the ARO-GR2 gives a fine aiming point for precise shot placement without obscuring small targets at distance. Holosun’s multi-reticle system lets you switch between single-dot and larger reticle options for fast acquisition or precision work. Green LEDs often offer better perceived brightness in daylight; paired with 12 brightness steps (including two NV-compatible settings), the ARO-GR2 adapts to bright sunlight, indoor ranges, and low-light scenarios.
Battery life and controls
Shake Awake™ technology reduces battery drain by powering the sight down when idle and instantly reactivating with movement — a practical feature for carry and occasional use. The simple control layout and clear brightness steps make dialing the correct setting rapid and intuitive in stress or competition.
