Holosun ARO RD2 1x Red Dot Sight – 2 MOA Dot Combo Kit with HM3X Magnifier & Hard Case

The Holosun ARO RD2 is an enclosed-emitter red dot sight designed for rifle and AR-15 shooters who need a rugged, weather-resistant optic for defensive, duty, or range use. This combo kit bundles the ARO sight with the HM3X magnifier, letting shooters flip between fast 1x target acquisition and magnified precision without swapping optics, all protected in an included hard case for storage and transport.

Built with a cast aluminum housing, the enclosed ARO design shields the emitter and lens from debris, moisture, and impact for reliable performance in harsh conditions. It runs on a single CR2032 battery and features Holosun's Shake Awake technology, which activates the reticle with motion and conserves battery life when the optic sits idle. The sight mounts to any Picatinny/Weaver rail for quick, secure installation on a rifle.
