The legendary PVS-4 Night Vision Weapon Sight is one of the most prolific night vision scopes ever made. Originally designed by Optic Electronic Corporation of Dallas in 1975, it was adopted by the U.S. Military in 1978 and served through 2008. That is an incredibly long time for a night vision device! The reason is that it is hard to beat, even by today’s standards. The PVS-4 utilizes a catadioptic lens system that gathers a tremendous amount of light. This provides incredibly clean and clear images, even in a Gen2 configuration. In fact, the Gen2 version looks almost as good as the Gen3 systems due to its lack of halo.
The PVS-4 can also serve as a Day/Night Sight. This is due to its innovative Day/Night Adapter. The adapter acts as a protective lens cover, but features a user-controllable aperture that allows the amount of light gathered to be regulated by the user. Three evenly-spaced holes are located around the periphery. As the dial on the front of the adapter is turned, different aperture sizes are lined up in front of the three holes. During daylight hours, the pinhole-sized apertures are used. At night, the apertures can be completely opened for use in semi-lit environments such as urban, or the adapter can be completely removed for use in total darkness. When the PVS-4 is used during the day, the image is still going to be green. While this may not be as ideal as using a standard dayscope, the ability to not have to change the scope between day and night is wonderful.
The TNV/PVS-4 is our version of this classic weapon sight. We start off with a completely refurbished and refinished original PVS-4 housing/optical system. There are no more PVS-4's being built, so anything available today is going to be "used.” However, these units are meticulously refurbished and upgraded. Parts are replaced and the entire system is just like new. The original systems were manufactured by Varo (Litton) We use new/unissued L3 MX-9644/UV Gen2 image intensifier tubes for the best possible resolution in their class. The reticle is fully adjustable for windage and elevation and features the standard M-16 pattern. This reticle features a range-estimator and a three-point cross hair that provides an aiming point for close range, 200m, and 400m.
The mounting interface on the TNV/PVS-4 has been upgraded from the original design. M1913 Picatinny Rail was not around in 1975, so the original PVS-4 was attached to weapons using proprietary brackets and mounts. Today’s modular weapon platforms feature much easier attachment methods. The TNV/PVS-4 has an excellent LaRue Tactical OEM LT100 quick detach mount. This incredibly solid mount allows users to add or remove the scope from standard M1913 rail without losing their zero.
Our TNV/PVS-4 also features an upgraded power supply. It runs off the ubiquitous CR123A 3-Volt Battery. This helps with commonality of batteries in the field since the majority of electronic devices use this power supply. It will also run off the old military button battery.
The TNV/PVS4 is a highly rugged day/night weapon sight. It is built like a tank and will stand up to plenty of abuse in the field. The incredible catadioptic lens system provides an incredible image when paired with its Gen2 tube. The lack of halo makes it especially effective in areas with light sources such as urban environments, while the large objective gathers enough light to make it very effective in complete darkness. The TNV/PVS-4 breathes new life into a classic system. This night vision weapon sight is perfect for hunters and professionals alike!
