Many modern scopes have a rail mounting system, that is in many ways safer and easier to use than traditional ring mounting. We can offer rail mounts for two of the most popular models: ZM-Rail and SR-Rail. The ZM-Rail (developed by Carl Zeiss) is used by Zeiss, Meopta, Schmidt & Bender and Leica. The SR-rail (developed by Swarovski) is used by Swarovski and Kahles. The Osuma rail mounts are available for 11mm rail, 17mm rail, Optilock base and Blaser mounting system.
