The Field Optics Research FM-200 Picatinny Rail Mount accepts several accessories, such as a telescopic sight or scope with the same Picatinny/Weaver mount. At the same time, this mount is compatible with most Arca-type clamps and with Manfrotto RC2/200PL quick-release assemblies, so you can place the mount onto a tripod. If neither quick-release system is present, you can still mount via the 1/4"-20 socket present on the bottom of the mount.
