Precision Meets Durability: A Closer Look at the Holosun ARO 2 MOA Red Dot Sight (ARO-RD2)
When it comes to fast target acquisition, rugged construction, and long-lasting performance, the Holosun ARO 2 MOA Red Dot Sight (ARO-RD2) stands out as a compact optic built for serious shooters. Whether you’re updating your current setup or looking for a reliable red dot to pair with your magnifier, the ARO-RD2 delivers next-level performance in a lightweight, efficient package.
An Evolution in Compact Optics
Building on the success of the widely popular 403 and 503 series, the ARO introduces a fresh design that enhances function without compromising form. Its new 22mm housing provides a broader field of view while maintaining a compact footprint.

Key Performance Features
🔋 Unmatched Battery Life
With up to 50,000 hours of battery life powered by a CR2032 battery, the ARO-RD2 ensures you're always mission-ready. Holosun’s renowned Shake Awake™ Technology conserves energy when the sight is not in use, and it quickly reactivates with motion. Even better, it recalls your last brightness setting—no need to readjust every time you power it back on.
🎯 Crystal Clear Precision
The ARO-RD2 is built for accuracy. Its 2 MOA red dot reticle, with a 650nm wavelength, provides a sharp aiming point that excels in both daylight and low-light conditions. You’ll have access to 12 brightness settings—10 for daylight and 2 for night vision—allowing for optimal clarity in any environment.

Weighing just 3.38 oz, this optic is crafted from durable aluminum and finished with a MAO (Micro-Arc Oxidation) coating for corrosion resistance. It’s IP67 rated waterproof, built to withstand submersion, and can handle vibration forces up to 1000G—making it as tough as your mission demands.
