Holosun continues to set the standard in red dot optics with the launch of the ARO and ARO EVO. Designed for versatility, durability, and reliability, these next-generation optics excel in both short- and intermediate-range engagements.
ARO Red Dots
The ARO (Advanced Rifle Optic) builds on the success of Holosun’s 403 and 503 series, featuring a 22mm housing that pairs seamlessly with Holosun’s magnifier series. It includes a 1.63-inch, 1/3 co-witness pedestal mount with a new skeletonized design. Equipped with Shake Awake Technology, a 50,000-hour battery life, and an IP67-rated water- and dust-resistant housing, the Advanced Rifle Optic is built for any environment. Its standout feature is the Multi-Reticle System (MRS), offering a 2 MOA dot, 65 MOA circle, or both, with Red, Green, or Gold illumination options to accommodate various lighting conditions and shooting preferences.
