The RVM-14 monocular housing is billet machined from 7075 aircraft grade aluminum and designed to handle challenging real-world environments. The housing design accepts Milspec PVS-14 eyepieces and C mount objective lenses. The monocular features a side mounting area to accept PVS-14 accessories and mounts with a standard ¼-20 thread. Two monos can also be attached to a bridge mount (RVM-14 Bridge) in a binocular configuration with the small dovetail incorporated into the top of the housing, or the dovetail can be used with the RVM-14 Arm for single mono use. Both the Arm and Bridge are articulating to lay back against the helmet when in the stowed position.
