The Holosun ARO (Advanced Rifle Optic) is a compact, rugged green dot sight designed for precision, speed and duty-grade reliability.

The optic is parallax-free, offers unlimited eye relief, and includes 12 brightness levels (10 daylight and 2 night vision), making it adaptable to any lighting environment.
