The FW-Solutions A14 J-ARM is the orignal articulating J-Arm design featuring the full articulation benefit for all tactical needs. This J-Arm features the proven adjustable dovetail concept made from 7075 T6 aluminum but also comes in a non adjustable version.In order to switch sides the user can unscrew the articulation joint as well as the dovetail and rotate them to match the other eye, if you plan to change your side frequently take a look at the A14 QS J-Arm.
 
Articulation has been used for dualtube setups for a long time but also mono units like the PVS-14 can benefit from the feature.Stowed close to the helmet the unit can reduce the counterweight required and will reduce neck strain since it is closer to the center of mass of your head/helmet. Getting in and out of vehicles or moving in confined spaces is also a lot easier due to the slimer profile.The user can also just rotate the nightvision in and out of his eyesight instead of flipping up the whole mount to allow for faster transition or deplyoment.
