The J-Arm attaches the AGM PVS-14 monocular to a standard-issue USGI Rhino Mount. It screws onto the PVS-14, lining up with electrical contacts. The J-Arm then causes the monocular's power to be shut off when you flip up the Rhino Mount, allowing for battery conservation and limiting visibility of the green glow emitted from the monocular lens.
