The Holosun ARO EVO is an enclosed rifle red dot sight with a large 26mm window and a clean 2 MOA dot — a step up in window size and features from the ARO MRS, with solar charging added. The sealed emitter keeps the dot running through dust and weather.
Solar Failsafe, Shake Awake, auto-brightness, Lockout Mode and a side-loading CR2032 tray give up to 50,000 hours of runtime and effortless readiness.
