HOLOSUN ARO-CORE Red Dot

The HOLOSUN ARO-CORE is a compact, enclosed red dot designed to offer rapid target acquisition, durability, and long battery life. Its 22 mm optical window provides a wide field of view within a compact body, while the 1x magnification and unlimited eye relief allow for natural and fast viewing.

The ARO-CORE series allows you to choose between a simple 2 MOA red dot reticle or the MRS (Multi-Reticle System) available with red, green, or gold illumination. The MRS variants allow you to select between a 2 MOA dot, a 65 MOA circle, or a circle-dot combination.

All models feature Shake Awake, setting memory, manual intensity control, and a CR2032 battery with up to 50,000 hours of battery life. The aluminum construction with a MAO finish and IP67 protection completes a package ready for intensive use.

Main features:
