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.

The ARO EVO, an enhanced version of the ARO, features a larger 26mm housing for an expanded sight picture. It introduces the Special Purpose Reticle (SPR), which combines a 2 MOA dot, a 65 MOA circle, and bullet drop compensation/ranging marks for improved versatility at intermediate ranges. Like the ARO, the EVO features Shake Awake Technology and a 50,000-hour battery life but also integrates Solar Failsafe within its durable 6061 aluminum housing. With IPX8-rated water and dust resistance and 8 daylight / 4 night vision brightness settings, the ARO EVO is designed for uncompromising performance in any environment.
