The Infiray Jerry-31 Night Vision Monocular is an ultra-lightweight, full-featured night vision binocular that features NNVT NVT4 1400-1600 FOM manual gain, non-autogated, white phosphor image intensifiers.

The NNVT intensifiers for the Jerry-31 are premium, hand-selected for the best screen cosmetics and performance. Weighing in at only 481g without battery, the Jerry-31 comes with a LOT of features you would expect from higher-priced, heavier offerings. The Jerry-31 is also extremely low-profile and significantly shorter than most other NVG binoculars on the market today - reducing the operator's overall head profile.

For a limited time, we are offering to install our Cold Harbour Converter Rings which will allow you to use any PVS-14 lens accessory such as our NV Defender or CHADs. Simply leave a note in the order comments! This allows you to Add front (objective) lens protection via our NV Defender lenses or CHAD iris devices.
