How to Build a PVS-14

How to assemble a PVS-14 night vision monocular.
The AN/PVS-14 Monocular Night Vision Device (MNVD) is an extremely versatile night vision monocular. It is one of the most widely used night vision devices by US armed forces. The PVS-14 can be used helmet-mounted, hand-held, or weapon mounted behind a night vision compatible red dot or holographic weapon sight like an Aimpoint or Eotech.

The PVS-14 uses a second or third generation image intensifier tube (MX-11769 or MX-10160 type).

Ultimate Night Vision is an industry leader in night vision, thermal imaging and digital NV devices. Night vision is not just a profession for us, it is our passion. Here in Texas, we are fortunate enough to be able to use NV and thermal scopes for hog hunting, coyote hunting, and hunting other predators and varmints at night. The firsthand knowledge gained through hunting with NVD's on a regular basis allows us to provide accurate and relevant information to our customers.
We carry a wide variety of optics from all major manufacturers including Trijicon, Pulsar, Flir, Armasight, L3, Harris and more. We strive to provide unbiased information to aid customers in the decision-making process. We also have a nationwide rental program which gives customers the unique opportunity to test and compare various devices under real-world conditions before committing to a large purchase.
Our channel features product reviews, instructional videos, comparisons, and plenty of actual hunting footage.

we’ve hit a pinnacle in NV / FLIR etc where costs are measured by competition. It’s exciting that the costs are starting to fall for some really superb NV.

[@AndrewZonenberg]

Do you normally use a torque driver with the housing screws, or just go by feel? And did you change gloves after greasing the objective lens threads? I didn't see that on camera and was concerned about you getting grease all over the optical surfaces.

[@tropicthndr]

It’s clean grease. Ha

You should watch this instead. Much better video and he speaks throughout and gives you a lot of invaluable information if you've never built NODS before. kzbin.info/www/bejne/rITYnp5mfcqBp8U

I have always wanted to know that. I'm proud of myself for accurately guessing some of the procedures and work environment necessary to work on nods. I was a little off but not by much.

[@mikethemaniac1]

Could Argon be used to purge optics such as this, or would it be an inferior or ineffective purging gas? I ask because it seems you'd have no reason to worry about the gas escaping if it were the purging gas, since argon is heavier than air.

[@claymore_roomba]

I would believe so yes,

[@spartanswill]

I know this is an old comment and I may be speaking from a point of ignorance, but wouldn't an argon gas leak in your face be very dangerous or even lethal? Wouldn't nitrogen be a better purging gas?

[@Timantinpoimija]

Random argon is not toxic it is inert. It is used as shielding gas for welding.

[@josephvanas6352]

in theory argon would be just as good as nitrogen there may be some expansion issues or something with it due to it being pretty heavy relative to air although i think the nitrogen purging is mostly to remove the oxygen so it may just be the cheapest option.

Definitely earned a new sub here!! Awesome video, but my question is where did you get the nifty little tools you used in this video for tightening up everything internally and the nitrogen purging equipment? I have an older pvs14 that needs some parts changed out but I have never ventured into doing it on my own and want to be sure to do it all correct and precise so any information would be greatly appreciated! Thank you for sharing!!

[@dylandailey7337]

did you ever find out what the tools are called?

[@mr.not.so.perfect.666]

The socket type retaining ring tools are not easily available from what I've seen, but you can use a Camera Lens wrench instead, and I bought one recently to take apart my own Monocular (not an PVS-14 though) since I didn't want to damage the retaining rings by using a screwdriver etc. Here's the link for the one I bought from Amazon. www.amazon.co.uk/gp/product/B00J5F6ZI2 Also in place of a proper Nitrogen purge kit you can use Nitrogen based wine preserver in a compressed air can, as long as it's Dry Nitrogen then is fine, also some people use Argon from a welding bottle as being heavier than air it forces the air out of the space within the monocular and replaces it with argon (it's the air that causes the condensation inside in places of high humidity, hot to cold environments). www.iwawine.com/wine-accessories-iwa/wine-openers-and-preservation/wine-preservation-systems

are all 18mm IIT's compatible between PVS-7 and PVS-14 bodies? I'm curious, because I've seen some "affordable" PVS-14 bodies for around the 500$ mark, and personally, I wouldn't mind throwing an older Gen2+ 18mm tube in it, but I also like the PVS-7 (though I haven't seen any bodies for those) Are there other cheaper 18mm IIT's say from russia or china that will work with PVS-7/14 bodies? I know there's a ton of elitists out there, I've used Gen3+ and I know how good it is, but I've also used older Gen2+ stuff and for what I need I think Gen2 will suffice *IF the price is right*

You cant upgrade the tube itself, but if you are somehow running a gen 1 in a pvs14 you can swap it out for a gen 2 no problem.

I broke mine too, the device will still function without the auto-off/on cable. Also it's probably not worth replacing, the auto off/on feature doesn't work well at all. I wouldn't trust the feature to protect my tube.

[@DaveSmith-cp5kj]

That entirely depends on if you can find the parts at a cheap enough price. You save a couple hundred dollars usually. This may or may not be worthwhile if you end up with crappy intensifiers that are blemished, or you want the warranty that a prebuilt device offers.

If you really are on a budget your best bet might be to make connections and try and source a used one. Make sure to get as much info on a tube before you buy. Sadly 3k is around the average these will go for at retail price. I just bought an MX11769 OMNI VII for $800, but that is a pretty rare deal.

Nitrogen purge is not completely necessary. The device will function without the Nitrogen. But with the Nitrogen Purge, it will remove any humidity build up inside the device and will also act as an anti-fog for the lenses.

[@DaveSmith-cp5kj]

Part of it is demand (few people are in the market for night vision as opposed to say a cell phone), the other part is that it is difficult to produce perfect devices every time. So a bunch are made and then sorted for quality. Consequentially it costs much more to build a good one.
