Innovative Ukrainian-made articulating J-Arm adapter engineered for mounting AN/PVS-14 night vision monoculars and equivalent systems equipped with a standard 1/4'' threaded socket onto helmet mounts. Featuring dual articulating joints, the accessory allows precise interpupillary alignment, fluid tilt control, and instant left-to-right eye transition without unthreading the optic.

Constructed from heavy-duty NYLON 12 engineering polymer paired with brass and stainless steel hardware, the adapter delivers structural strength while maintaining an ultralight profile (weighing only 52 g). Designed with a standard Dovetail interface, it interfaces smoothly with professional helmet mounts (Wilcox, Norotos). An integrated lanyard/bungee tether loop provides supplemental tension management to eliminate system movement during dynamic movement.

Key advantages

Dual-articulating joint system for precise optical positioning and eye relief control
Seamless left or right eye operational swapping in a single motion
Low-profile stow capability keeping the optic close to the helmet shell to prevent snagging
Rigid lockup in Dovetail interface helmet mounts
Integrated bungee retention loop for eliminating mount play during active movement
Constructed from high-grade NYLON 12, stainless steel, and brass
Lightweight form factor (52 g) manufactured in Ukraine
