An articulating J-arm adapter by Ukrainian manufacturer UDAPT for attaching an AN/PVS-14 night vision monocular to a helmet mount with a dovetail interface. It combines full articulation with automatic device shut-off when flipped to the stowed position. Body made of anodized 7075 aluminum and TC4 titanium, weighing 57 g.

The adapter consists of movable hinged sections that let you swing the monocular out of the field of view or move it between the left and right eye in a single motion. The hinges reduce impact load transfer to the device and the neck on contact — unlike rigid metal mounts, while plastic designs do not withstand comparable loads. The adjustable UDAPT Dovetail connector takes up play in the mount interface. The offset design brings the monocular closer to the eye, widening the field of view and shielding eyepiece glow. Flipping the middle section increases the distance from the face by 10 mm for use with a gas mask. A dedicated loop allows the adapter to be additionally secured to the helmet with a bungee cord.

Key Advantages

Automatic device shut-off when flipped to the stowed position (works in left-eye configuration only)
Adjustable dovetail connector eliminates play in the mount interface
Quick flip-up and transfer of the monocular between left and right eye
Compact stowed position — the device sits close to the helmet, reducing the risk of snagging
Offset design brings the eyepiece closer to the eye and shields eyepiece glow
+10 mm face clearance for gas mask use (middle section flip)
Bungee cord loop for additional retention
7075 aluminum and TC4 titanium — high strength at 57 g
