The Vortex Micro 3x Magnifier (V3XM) is a fixed 3x magnifier built to flip in behind a red dot sight, extending its effective range without swapping optics. It has a 22mm objective lens with fully multi-coated glass for increased light transmission, an exit pupil of 7.33mm, and eye relief of 2.64 inches. Diopter adjustment runs from -2.5 to +2.5 dpt to dial in focus for the shooter's eye. Angular field of view is 7.28 degrees, which works out to a linear field of view of 38.2 feet at 100 yards. The magnifier mounts via an integrated quick-release flip mount, allowing it to be set up for absolute co-witness at 1.46 inches from base to optic center or lower 1/3 co-witness at 1.57 inches from base to optic center with the included riser plate. A rubber lens cover, lens cloth, 3mm hex tool, and lower 1/3 co-witness shim are included. Built from machined aluminum with a matte black anodized finish, the unit measures 2.9 inches long, 0.86 inches wide, and 47.75mm tall, and weighs 9.55 ounces with the mount installed. It is waterproof and nitrogen-purged for fogproof performance.
