Holosun® ARO GD2 Gold Dot Sight

The Holosun^® ARO GD2 Gold Dot Sight sets a new standard for compact optics. Featuring a modern design, a larger 22 mm objective lens, and a crisp 2 MOA gold dot reticle, it combines speed, precision, and durability. With its aerospace-grade aluminum housing, precise machining, and T2 footprint compatibility, the ARO GD2 is built to perform—no compromises, no delays.

Wider Objective, Greater Field of View

The ARO GD2 expands on the proven HS403/HS503 series with a 22 mm objective lens for improved clarity and magnifier compatibility. The enlarged field of view provides rapid target acquisition without restricting peripheral vision—ideal for both precision shots and fast-paced engagements.

Smart Energy Management

Equipped with ShakeAwake™ motion-sensing technology, the sight powers down when idle and instantly reactivates at the slightest movement. Powered by a reliable CR2032 battery, it offers up to 50,000 hours of runtime. Automatic brightness adjustment and last-setting memory ensure readiness in every scenario.

Seamless Compatibility

The optic comes with a high mount (lower 1/3 co-witness, 1.63″) and uses the industry-standard T2 footprint, ensuring compatibility with a wide range of aftermarket mounts. This guarantees a stable, modular setup without the need for modifications.

Precision in Gold

The 2 MOA gold dot reticle delivers quick and accurate aiming, while distortion-free aspherical glass ensures a crisp, clear image. With 12 brightness settings—including 2 night vision modes—the sight adapts to any lighting condition with ease.
