Holosun ARO-RD2 Enclosed 2 MOA Red Dot Sight – Black – ARO-RD2

The Holosun ARO-RD2 is engineered for shooters who demand a simple, precise, and durable red dot optic. Its clean 2 MOA red dot delivers fast target acquisition and precise aiming for both close-quarters and mid-range shooting applications.

Constructed from 7075-T6 aluminum with a matte black hard-anodized finish, the optic is IP67 waterproof and built to handle heavy recoil and harsh field conditions. The fully multi-coated lens provides a bright, clear sight picture, while the enclosed emitter design ensures consistent performance in all weather.

This model runs on a single CR2032 battery, offering up to 50,000 hours of operation at setting 6. Shake Awake™ technology turns the sight on with motion and powers it down after inactivity to extend battery life, while retaining the last brightness setting used.

With 12 brightness levels—10 for daylight and 2 night-vision compatible—the ARO-RD2 adapts to any lighting condition. Windage and elevation adjustments provide ±50 MOA of travel in 0.5 MOA click increments for precise zeroing.

The optic includes a Picatinny mount configured for lower 1/3 co-witness with standard AR sights, plus an additional low mount for alternate setups.
