Check out Black Optex new product – the Zero Lens!

The Zero Lens is an optical alignment kit that enables the use of a PVS-14 night vision monocular to be mounted in front of day optic and allow nighttime engagement capability with no shift of your point of impact.  Mounting the PVS-14 in front of the optic is more efficient and user friendly than when the PVS-14 is mounted behind the primary sight.  Image intensification efficiency of the PVS-14 is maintained by front mounting, and resolution of the produced image is improved as it passes through the Zero Lens. Front mounting also allows the operator to maintain the same shooting position, muscle memory, and eye relief with his primary sight.

The standard quick detach mounting system enables rapid installation and removal, allowing easy transition of the PVS-14 between handheld, helmet mounted, or weapon mounted use as needed during operations. Once set, the Zero Lens will maintain alignment between the day sight and the adjusted PVS-14 when it is re-installed.

The Zero Lens is a rugged, non-electronic, compact device that adds capability to your existing inventory of optics at a fraction of the cost of adding new stand alone systems. For more details visit or Black by click on the link below.
