Holosun ARO-RD2 Advanced Rifle Optic – 2 MOA Red Dot

The Holosun ARO-RD2 is a compact, lightweight red dot sight that advances the proven 20mm Holosun 403 and 503 series with a new 22mm housing for expanded field of view and optimal compatibility with magnifiers. Engineered for agility and precision, the ARO-RD2 features a crisp 2 MOA red dot, rugged aluminum construction, and the reliability shooters trust from Holosun optics.

Built with Shake Awake™ Technology and offering up to 50,000 hours of battery life on a single CR2032, this optic stays ready when you are — whether you’re running drills at the range or storing your firearm for home defense. The ARO’s lower 1/3 co-witness mount ensures comfortable alignment with your backup iron sights, and its updated design pairs perfectly with Holosun magnifiers for enhanced versatility.

Its intuitive motion-sensing system powers the LED off when not in use and back on instantly with the slightest motion, ensuring the dot is always ready without fumbling with buttons. Lightweight, durable, and field-ready — the ARO-RD2 is an ideal upgrade for any AR or PCC platform.
