The Vector Optics MAG Red Dot Lower 1/3 Co-Witness Cantilever Weaver Polymer Mount is a compact, lightweight mounting solution designed for real firearms. It features a 28 mm (1.1 in) saddle height profile and a cantilever-style body, giving shooters a 1/3 lower co-witness setup when paired with a compatible red dot sight. The mount uses a 21 mm Weaver interface, and its overall design is intended to keep the optic positioned securely while maintaining a practical, low-profile configuration.

At the top, the mount uses the MAG footprint, which is RMS-c compatible, and it is designed to fit the Vector Optics Frenzy-S MIC and AUT red dot sights. The receiver plate measures 40.8 mm (1.6 in), while the mount itself is 36 mm (1.4 in) long and 28 mm (1.1 in) high. Made from plastic polymer, it weighs only 23 g (0.8 oz), making it a compact and light choice for shooters who want a durable but unobtrusive mounting option. The mount has a Weaver attachment and a black matte finish, completing a clean and functional look.
