I am currently on vacation and products from my shop will be unavailable for next few weeks. Thank you for your patience and apologize for any inconvenience.
ARO (Advanced Rifle Optic) is an upgrade from Holosun’s popular 20mm 403 and 503 series optics. ARO features a new 22mm housing design that fits perfectly with their magnifier series and a 1.63-inch lower 1/3 co-witness pedestal mount.
