Holosun ARO Red 2 MOA Dot 1x
810047073598 MPN: ARO-RD2 The Holosun ARO red dot sight is the Advanced Rifle Optic, representing a refined evolution of Holosun's trusted 403 and 503 series with thoughtful upgrades tailored for modern rifle use. It delivers 1x magnification through a bright, precise red 2 MOA dot reticle, powered by Holosun's efficient LED technology for clear visibility in any lighting condition - from bright daylight to low-light environments. The expanded 22mm objective lens diameter provides a wider field of view than traditional 20mm designs, improving target awareness and faster acquisition, all packed into a compact 2.48-inch overall length. The matte black anodized finish on its high-grade aluminum housing ensures rugged durability against recoil, impacts, and harsh field conditions. Built for seamless integration on AR platforms, carbines, and other rifles, the ARO includes a dedicated 1.63-inch lower 1/3 co-witness pedestal mount that aligns perfectly with standard backup iron sights for quick transitions when needed. Its new 22mm housing design mates flawlessly with Holosun magnifiers, allowing shooters to add variable magnification for extended-range capability without compromising the optic's low-profile setup. Holosun's proven Shake Awake technology automatically activates the reticle with motion detection and powers down during periods of inactivity, maximizing battery efficiency so the sight is always ready when you are. Whether configuring a duty rifle, competition build, home defense setup, or training carbine, the Holosun ARO stands out as a high-value, reliable red dot upgrade that blends familiar Holosun performance with enhanced optics and mounting versatility. The multilayer reflective glass delivers crisp, distortion-free reticle projection with parallax-free viewing and unlimited eye relief, supporting intuitive both-eyes-open shooting. Multiple brightness settings adapt to diverse scenarios, while the included pedestal mount offers immediate Picatinny compatibility and magnifier pairing options. (Mount included; compatible with Picatinny rails and Holosun magnifiers for added flexibility.)
