The Holosun ARO-EVO-SPR-RD  is a rugged red dot optic designed with a 26mm housing for an expanded field of view and faster target acquisition. Powered by a CR2032 battery with solar support and Shake Awake technology, it delivers up to 50,000 hours of runtime. The Special Purpose Reticle (SPR) combines a 2 MOA dot with bullet-drop compensation, making it effective for mid-range accuracy. With 12 brightness settings—eight for daylight and four for night vision—it offers adaptability in various lighting conditions. Built from durable 6061 aluminum, the ARO-EVO is IPX8 waterproof, corrosion-resistant, and functional in temperatures ranging from -30℃ to 60℃. It also includes a lower 1/3 co-witness mount, lens cap, and anti-reflection device for enhanced performance.

The combo also includes the Holosun HM3X magnifier, adding 3X magnification for better target clarity. It includes an ambidextrous flip-to-side Picatinny mount with a quick-release mechanism and a spacer for compatibility with both absolute and lower 1/3 co-witness heights. A built-in flat driver tool simplifies on-the-go adjustments, making this combo a practical upgrade for any shooter.
