ARO features an all-new 22mm housing design that mates perfectly with our magnifier series, an all-new 1.63” lower 1/3 co-witness pedestal mount, and compatibility with a new lens cover and anti-reflection device system (available separately). The ARO series is available as a 2MOA dot only or with our Multi-Reticle System (MRS) in Red, Green, or Gold dot colors.
