HOLOSUN ARO-CORE-RD-2 – Enclosed 2 MOA Red Dot Sight | Black
The Holosun ARO-CORE-RD-2 is a compact, lightweight enclosed red dot sight designed for modern rifle platforms. It combines a precise 2 MOA red dot, a refined 22 mm viewing window and an MAO-finished aluminum housing to provide a reliable, versatile optic for sport shooting, training and compact rifle configurations.
Its Shake Awake system activates illumination when motion is detected and automatically powers down during inactivity to preserve battery life. The CR2032 battery is housed in a side-loading tray, allowing replacement without removing the optic from its mount. Manual brightness adjustment offers 10 daylight settings and two night-vision-compatible settings, while the two included mounts support either low or lower 1/3 co-witness installation.
