Holosun ARO-CORE 2 MOA Green Dot Sight with HM3X 3X Magnifier The Holosun ARO-CORE and HM3X bundle combines a 2 MOA green dot sight with a separate 3X magnifier. The ARO-CORE provides an unmagnified view through its 22mm optical window, while the HM3X adds a magnified view when positioned behind the sight. Its quick-release flip-to-side mount keeps both viewing options in one optic setup. Shake Awake controls illumination in response to motion and inactivity, reducing the need to leave the sight continuously illuminated. A side-loading CR2032 battery tray makes battery changes possible without removing the sight from its mount. Manual brightness control provides ten daylight levels and two night-vision-compatible levels. The included low and lower 1/3 co-witness mounts offer two sight-height options for compatible Picatinny setups. Key Features Green aiming dot: A single 2 MOA dot defines this reticle configuration. HM3X magnifier: 3X magnification with a quick-release flip-to-side mount. Motion-controlled illumination: Shake Awake and automatic shutoff help manage battery use. Aluminum housings: Both the ARO-CORE sight and HM3X magnifier use aluminum bodies.
