Description:
This night vision J-arm for both the MILSPEC AN/PVS-14 and other monoculars that accept a MILSPEC j-arm such as the AB Night Vision RVM-14 and Nocturn Industries UANVM “TANTO” monocular. It includes a rotating knuckle which provides a tight stow against the helmet and also allows the monocular to be temporarily swung away from the eye. 
An intuitive, friction-based mechanism allows users to swing their monocular in front of either the left or right eye and perfectly adjust for interpupillary distance, while a slight rearward sweep of the inner arm helps position the monocular eyepiece closer to one's eye and provides greater compatibility for those with larger helmets. A tether point is also featured on the rear to keep the entire system secure. Attach a monocular, snap the complete assembly into a dovetail-style helmet mount like the G24, and enjoy. 
Considerations to account for when using this product:
This arm is NOT COMPATIBLE with USGI bayonet helmet mounts such as the legacy Norotos Rhino or L4 G11. You MUST HAVE a dovetail helmet mount such as the L4 G24.
The USGI auto-shutoff system is not integrated. Users must manually turn off the monocular when articulating or flipping up and stowing equipment on top of the helmet.
