The Cantilever 30mm Ring from Vortex is a riflescope accessory that provides 1" of additional rail space by offsetting the mounted optic. A Lower 1/3 Co-Witness mounting height allows the shooter to co-witness their front sight using the attached optic. Vortex's cantilever ring mount is compatible with most 30mm red dot sights and it has an integrated Picatinny rail mount.
