Holosun ARO MRS Gold Multi-Reticle 2 MOA/65 MOA 22mm

Holosun ARO MRS Enclosed Rifle Sight – Gold Multi-Reticle is a compact, enclosed 1x reflex optic designed for rifle and carbine platforms. Built by Holosun, it provides a selectable gold reticle system that can be configured as a precise 2 MOA dot, a large 65 MOA circle, or a combined circle-dot for fast, repeatable sighting.

The ARO MRS is engineered to deliver a clear, unobstructed sight picture while maintaining a low-profile footprint suitable for modern AR-style rifles. Its enclosed design protects the emitter and optics from dust, debris, and weather, making it a practical choice for patrol, duty, and range rifles. With a 22mm objective lens and unlimited eye relief, the optic supports dynamic shooting and rapid transitions, and it can be paired with magnifiers when extended-range capability is required.

Specifications & Construction

The ARO MRS features an enclosed housing machined from anodized 6061 aluminum with a black matte finish. It operates at 1x magnification and uses a 22mm objective lens with multi-coated optics. Reticle options include a 2 MOA dot and a 65 MOA circle in gold illumination. Power is supplied by a single CR2032 battery. Listed weight is approximately 5.56 oz. Environmental protection is rated at IP67 for dust and water resistance, with a manufacturer-specified high recoil tolerance.

Compatibility & Intended Use

Designed to mount to standard 1913 Picatinny rails (Picatinny/Weaver footprint), the ARO MRS is intended as a primary non-magnified optic on AR-pattern rifles and similar platforms. It ships with mounting options that support lower 1/3 co-witness configurations and alternative optic heights, making it suitable for use with backup iron sights or in combination with a magnifier for extended-range roles.
