The Holosun ARO (Advanced Rifle Optic) builds on the success of the 20mm 403 and 503 series with an all-new 22mm housing design and a 1.63″ lower 1/3 co-witness pedestal mount. The Multi-Reticle System (MRS) provides three aiming options: a 65 MOA circle with a 2 MOA dot, a standalone 2 MOA dot, or a standalone 65 MOA circle, all rendered in crisp green illumination. The green reticle delivers enhanced visibility across varied backgrounds for quick target acquisition.
The ARO-MRS-GR features a durable aluminum housing with hard anodized coating, engineered to handle demanding conditions and rated IP67 for water and dust resistance. Shake Awake Technology automatically powers down the LED when the optic is stationary and reactivates upon motion, shutting off completely after 10 minutes without movement to conserve battery life. A CR2032 battery provides up to 50,000 hours of operation at mid-level brightness. Ten brightness settings—including two dedicated to night vision compatibility—and unlimited eye relief round out this optic’s feature set for rugged reliability.
