CNC Machined Dual Binocular Bridge NVG Mount + AN/PVS-14 J Arm Dovetail Adapter. Brand new and high quality. Constructed of CNC machined aluminum. The bridge system interfaces with standard dovetail mounts such as the popular L4G24. The binocular bridge system for the Oasys SkeetIR and IR Patrol allows users to head-mount these thermal monoculars for hands-free application. When used in binocular mode, the Bridge allows operators to set the inter-pupillary distance with a stop plate. It is easily adjusted with a thumbscrew and prevents the optic from overshooting the eye when placed in operational position. AN/PVS-14 binocular bridge j arm attaches directly to a PVS-14 night vision monocular. It provides a dovetail interface that clips into the AN/PVS-14 binocular bridge folding Arm. This j arm is one of the parts necessary when converting a bridge mount set up for a single PVS-14 into one that will accept two monoculars. It will also allow users to attach a PVS-14 night vision monocular to the bridge mount for the Oasys SkeetIR and IR Defense IR Patrol. L4 G24 NVG mount and night vision goggle are not include. Due to the lighting effect, there may be color difference in the pictures taken. Q: The logistics information shows that the package has been delivered, but I have not received it. What should I do?
