Upgrade your Mini MH25 or Mini ML19 Thermal Monocular with the PVS-14 Eyepiece. This accessory increases the eye relief on these devices as well as the interpupillary divergence, and decreases the perceived optical magnification to 1x. These advantages are most evident and useful when the MH25 and ML19 are helmet mounted, and its simple thread-on design makes installation fast and easy.
