Holosun ARO MRS Red Dot Sight 2 MOA 65 MOA Circle Enclosed Multi Reticle System

The Holosun ARO CORE (Advanced Rifle Optic Core) represents the next evolution of compact rifle optics from Holosun, building upon the success of the widely trusted 20mm 403 and 503 series. Designed specifically for modern sporting rifles, the ARO CORE introduces a refined 22mm enclosed housing that enhances durability while maintaining a lightweight, streamlined footprint. Engineered for real-world rifle use, the optic ships with a 1.63-inch lower 1/3 co-witness pedestal mount, providing a natural sight picture with AR-pattern rifles and allowing shooters to maintain a clear field of view above backup iron sights. The enlarged optical window improves situational awareness and target tracking while preserving the fast target acquisition shooters expect from a compact red dot platform. Built with compatibility in mind, the ARO CORE’s housing geometry integrates seamlessly with Holosun’s magnifier lineup, allowing shooters to quickly transition between close-quarters speed and extended-range precision.  The defining feature of this configuration is Holosun’s Multi-Reticle System (MRS), which allows shooters to choose between multiple reticle options depending on mission requirements. Users can switch between a precise 2 MOA red dot, a 65 MOA circle, or a combined circle-dot reticle. This flexibility enables fast acquisition at close range while maintaining precise aiming capability for distance shooting.
