Holosun ARO

The Holosun ARO (Advanced Reflex Optic) represents Holosun's direct answer to the Aimpoint Duty RDS, delivering enclosed emitter protection in a compact micro footprint with Aimpoint Micro T-series mount compatibility. Released in 2024, the ARO combines the reliability of an enclosed emitter design with Holosun's proven feature set—shake-awake, last setting recall, and exceptional battery life—all at approximately $100 less than the FBI-selected Aimpoint Duty RDS.

The ARO features a fully enclosed housing that protects the LED emitter from rain, snow, mud, and debris, eliminating the primary vulnerability of open-emitter red dots. The crisp 2 MOA red dot provides the ideal balance between precision and speed, visible across 12 brightness settings including 2 night vision compatible levels. Holosun's Shake Awake technology automatically powers down the optic after 8 minutes of inactivity and instantly reactivates upon detecting motion, while Last Setting Recall ensures the optic returns to your preferred brightness when powered on.

Built from 7075-T6 aluminum alloy with an anodized finish, the ARO is submersible to IP67 standards and operates reliably in extreme temperatures. The Aimpoint Micro footprint ensures compatibility with the industry's largest ecosystem of mounts, from budget risers to premium quick-detach systems. With 50,000 hours of battery life on a single CR2032—over 5 years of continuous operation—the ARO delivers set-and-forget reliability. For shooters seeking Aimpoint-style enclosed protection with Holosun features at mid-tier pricing, the ARO competes directly with the Duty RDS on performance while undercutting on price.
