This tMA-50 Clip-On Adapter allows the Swarovski tM 35 Thermal Monocular to be very easily converted from a handheld device to a clip-on device. Together with your 50mm objective-lens riflescope, the thermal imaging device creates a powerful combination that requires no sighting in and guarantees a 100% reliable point of impact, each and every time. The tMA thermal monocular adapter is compatible with SWAROVSKI OPTIK Z8i, Z6i, Z5(i), and Z3 riflescopes.Swarovski Demo ProductsSwarovski demo products have been slightly used for display or demonstrations by Swarovski during outdoor industry events.
