Description
The Holosun ARO-CORE (Advanced Rifle Optic Core) is an evolution of the popular 20mm 403 and 503 series, built around an all-new 22mm enclosed housing that mates perfectly with Holosun's magnifier series and a new 1.63″ lower 1/3 co-witness pedestal mount. This MRS model features the Multi-Reticle System, letting you select a 2 MOA dot for precision, a 65 MOA circle for rapid acquisition, or a circle-dot combination for the best of both.
The aluminum housing with MAO finish delivers IP67 waterproofing and 1000G vibration resistance, while Shake Awake with Lockout Mode and a side-loading CR2032 battery (up to 50,000 hours) keep the optic ready and simple to maintain. Each sight ships with both a 1.63″ lower 1/3 mount and a 1.05″ low mount. Available in Red, Green, or Gold reticle.
