The ARO-EVO-GR-2 combines a highly visible 2 MOA green dot with a large 26mm viewing window for fast target acquisition and improved situational awareness. The expanded optical window provides a clear sight picture while maintaining a precise aiming point for a wide range of shooting applications. Built for dependable performance, the ARO-EVO-GR-2 uses a hard-anodized 6061 aluminum housing with IPX8 waterproof protection and 1000G vibration resistance. Its adaptive brightness system automatically responds to ambient lighting, while manual controls provide direct brightness adjustment when needed. Solar Failsafe supplements battery operation, and Shake Awake technology activates the optic when movement is detected before powering down during inactivity. The side-loading CR2032 battery tray allows replacement without removing the optic from the rifle. Eight daylight and four night vision compatible brightness settings, plus lockout mode, provide additional control over the reticle.
