Holosun® ARO EVO RD2 reflex sight

Holosun ARO EVO RD2 is the new generation of enclosed micro reflex sights, built on the experience of the 403/503 series. It offers a clear image, immediate response and reliability in any environment. It combines modern design, solar technology and durability that you can rely on. With a 26 mm diameter, it offers a wide field of view and quick target acquisition – an ideal choice for both sports and tactical shooting.

An evolution that makes sense

The ARO EVO RD2 was developed as a natural progression from the previous generation of Holosun sights. The new body features clean lines, improved ergonomics, and a lightweight "I" shape mount that ensures maximum visibility. The design is not just for looks – every edge has its purpose. The result is a durable, functional and visually balanced optic for all types of firearms.

Precise dot, quick targeting

The 2 MOA red dot reticle allows for precise aiming regardless of distance. The brightness remains consistent and the image is clear and distortion-free thanks to aspheric glass. The ARO EVO RD2 speeds up shooting – simply cover the target with the dot and pull the trigger. No parallax, no need to align the eye, just simple aiming.

Solar power in action

The sight uses Solar FailSafe technology – it can draw energy from light and switch between solar power and battery depending on the situation. The CR2032 battery lasts for tens of thousands of hours. The ShakeAwake technology monitors the movement of the gun and wakes up the sight precisely when you pick it up.

Visibility in any light

Twelve brightness levels, including four night vision modes, ensure the reticle is readable in any environment. The electronics respond smoothly, handling transitions between light and shadow without flicker. The 26mm field of view provides clear oversight, whether it’s for a quick target at the shooting range or hunting in low light.

Compatibility without limitations

The ARO EVO RD2 has a T2 footprint and a lower 1/3 co-witness mount (1.63"), suitable for Picatinny and Weaver rails. It works seamlessly with mounts from other manufacturers. With its universal attachment and lightweight construction, it’s suitable for rifles, shotguns and AR platforms.

Durability and assurance

The aluminum alloy body withstands the recoil of high-caliber firearms while protecting the internal optics from water, dust and shocks. The electronics are stable and the seals are tight even in extreme conditions. The RD2 simply holds – on the range, in the field and in the rain.
