Holosun ARO Enclosed Gold 2 MOA Rifle Sight

Holosun ARO Enclosed Gold 2 MOA Rifle Sight is a compact, enclosed 1x reflex optic designed to provide fast, repeatable aiming on rifle platforms. Manufactured by Holosun, it features a gold 2 MOA dot reticle that offers a precise point of aim while remaining highly visible in varied lighting conditions.

The ARO is built to address the need for a durable, low-profile rifle optic that integrates cleanly with magnifier systems and standard backup iron sights. Its enclosed 22mm aluminum housing protects the emitter and electronics from debris and environmental exposure, making it suitable for general-purpose rifles, range use, and training setups. The included lower 1/3 co-witness pedestal mount positions the optic at a height compatible with many iron sight configurations while maintaining a natural sight picture.
