The Holosun ARO-CORE-MRS-RD is a compact, enclosed rifle optic that brings Holosun’s proven Multi-Reticle System (MRS) to the next-generation ARO-CORE platform. Featuring a selectable 2 MOA dot, 65 MOA circle, or circle-dot combination, this optic gives shooters the versatility to prioritize speed with the large circle for close-range engagements or precision with the crisp dot for longer shots.
Built around a refined 22mm optical window, the ARO-CORE-MRS-RD delivers a clear sight picture with excellent light transmission and minimal parallax. Holosun’s Shake Awake technology instantly activates the reticle on motion detection while conserving battery life during downtime, paired with a side-loading CR2032 battery for quick changes without removing the optic. It offers 10 daylight and 2 night-vision compatible brightness settings, plus Lockout Mode to prevent accidental adjustments.
Constructed from rugged MAO-finished aluminum with IP67 waterproof and dustproof ratings, this optic is built to handle recoil, harsh environments, and rough handling. It includes both a 1.63″ lower 1/3 co-witness mount and a 1.05″ low mount for flexible setup on ARs, carbines, and other platforms. Lightweight yet durable, the ARO-CORE-MRS-RD is an outstanding value for duty, home defense, or recreational shooters seeking reliable performance without compromise.
