Holosun ARO First Impressions – Is This the 403 Replacement We’ve Been Waiting For?
The Holosun ARO (Advanced Rifle Optic) is presented as a potential successor to the 403B series. Initial impressions highlight its sleek design, 1/3 co-witness height (1.63 inches), and the availability of a yellow reticle option alongside red and green. The optic features a simple 2 MOA dot and uses buttons for brightness control, moving away from the traditional wheel. It has been tested for NVG compatibility and held zero through approximately 200-300 rounds.
