The Holosun ARO-EVO SPR Green is built for shooters who demand more than a simple red dot. Designed as part of Holosun's Advanced Rifle Optic (ARO) line, this enclosed reflex sight delivers a larger 26mm window, enhanced durability, and a purpose-driven reticle system tailored for modern 5.56 platforms. At its core is Holosun's SPR (Special Purpose Reticle), engineered specifically around M193 5.56 NATO ammunition at 3,050 FPS. Whether you're running drills inside 50 yards or stretching distance with practical holdovers, the ARO-EVO SPR gives you intuitive bullet drop compensation in a compact, enclosed package. The result is a rifle optic that balances speed, precision, and environmental resilience without compromise. The SPR (Special Purpose Reticle) system combines a precise 1.5 MOA green center dot, three 1 MOA holdovers, a 65 MOA outer circle, and integrated ranging features to deliver rapid close-range acquisition with confident extended-distance holds-without the need to dial adjustments. A generous 26mm viewing window enhances situational awareness and speeds transitions during dynamic rifle work, while the enclosed emitter design protects against dust, rain, carbon, and debris for consistent performance in harsh conditions. The green reticle improves daylight visibility and adapts to changing light with multiple brightness settings, and its BDC layout is purpose-built around M193 55gr 5.56 at 3,050 FPS for practical use on common AR-15 platforms.
