The Holosun ARO 2 MOA Red Dot Sight with HM3X Magnifier and Lower 1/3 Mount, Black is a magnifier that fits 1913 Picatinny Rail.
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. ARO is available as a 2MOA dot only or with their Multi-Reticle System (MRS) in Red, Green, or Gold.
A magnifier sits behind a red dot or holographic sight to add magnification, and flips to the side when you want the unmagnified view. Check the mount height matches your sight.
