So I had a Night Detective Quest 5 (ND-Q5) Night Vision Monocular for a while. I used it to watch nocturnal animals and shoot photographs of them. Recently, I had gotten into airsoft, so I've been experimenting with this night vision monocular. This article documents my experimentation. The photo below is the 5x night vision monocular.

This article documents the usage of the Night Detective Quest 5 (ND-Q5) Night Vision Monocular on airsoft guns. It doesn't talk about the monocular itself. However, take a look at the "Night Detective Quest 5 (ND-Q5) Night Vision Monocular Review" article to learn more about the monocular.
The first idea I had was to use the night vision monocular for observation. It is useful in the dark to identify enemies on the field. It's very useful during an indoor light-out game, or a night MilSim operation on an outdoor field.
You can already use the monocular by itself. Just pull it out of your bag, your pants pocket, or where ever you carry it. But getting it out slows you down. So the idea is to attach it to your gun. Your airsoft gun is always in your hand. Having the monocular on the airsoft gun gives you quick and easy access to survey the field in the dark.
I preferred coming up with a way to attach the monocular to the picatinny rail on the gun. But couldn't really find any parts that would help. So I settled with hockey tape (see photo below). Wrapping the hockey tape around the monocular and the M4 quad-rail supported its weight.
I was able to view the night vision scope my moving my paintball mask up to the eyepiece. The clear paintball pane provided just the right distance to get a clearview through the eye-piece. And it has just enough clearance to right, which allow me to fit my paintball facemask without the gun getting in the way. The photo below shows the monocular attached to my Shark Raptor from the top.

The Shark Raptor is a custom airsoft gun I built in the "Build a Science Fiction Airsoft Gun" article.
The photo below shows the entire Shark Raptor and the monocular. The monocular is quite heavy, so on a short gun like the Shark Raptor, it's a little off balance. But I had no problem holding it up and using it for battle.
In practical use, I found the 5x magnification to be too much for an indoor CQB field. I was able to see things in the dark clearly. But the field-of-view (FOV) was too narrow for it to be much of use. It'd be more usable with less magnification or no magnification at all.
Since I had limited success with this monocular on an indoor CQB airsoft gun, I decided to try turning my red dot scope into a night vision scope on my outdoor gun. My outdoor gun happens to be a JG M5-S6; surprise, surprise! Yes, the MP5-SD3 is longer than the Shark Raptor, so I use it for outdoor battles.
Cross Reference
You can take a look at how long the JG M5-S6 compares to the APS Mini Patriot M4, which is the exact same size as the Shark Raptor, in this "Size Comparison: APS ASR106 Patriot M4 vs. JG M5-S6 MP5" article.
The following photo shows my JG M5-S6 with the NcStar Tactical Red/Green Dot Sight with 30mm Cantilever Weaver Mount (DMRG130) and the Avengers Tactical 3X Magnifier already configured on the gun. The 1" riser and the 1/2" offset riser is normally not needed. But they are necessary in order for the monocular to work. It's difficult to see, but I have added the Aim Sports MP5/H and K Scope Mount to the MP5, so that this setup would work. (All these parts are reviewed elsewhere on this site as well.)
The idea is that the 5x monocular would replace the Avengers Tactical 3X Magnifier during night missions. The configuration could be changed quickly and easily. In order to accomplish these goals, I ordered an 1" offset riser, with quick release thumbscrews, for the monocular. I had a bunch of white sport tape lying around, so I taped the monocular to the riser for prototyping (see photo below).
The photo below shows the MP5-SD3 with the night vision monocular as an optional attachment. From the picture, it's difficult to see how the monocular would attach.
But have no fret, the night vision monocular is attachable with a comfortable clearing after the Avengers Tactical 3X Magnifier has been flipped to the side. The photo shows the monocular attached to the gun. The quick release thumbscrews makes it a quick and easy attachment. The 1" offset riser under the monocular and the 1/2" offset riser under the NcStar Tactical Red/Green Dot Sight with 30mm Cantilever Weaver Mount (DMRG130) line up the red/green dot perfectly in the center of the night vision monocular.
From the other side of the gun, you can see that the Avengers Tactical 3X Magnifier has been flipped to the side. Unless you have a way to protect the Avengers Tactical 3X Magnifier lens element from BB hits, you don't really want to keep it flipped to the side; it's better to remove the Avengers Tactical 3X Magnifier from the gun during night missions.
The photo below shows the night vision configuration of the entire gun. As you can see, it adds significant bulk to the gun. But it's worth it in a nighttime special operation.
I have tried this configuration in the dark. The red/green dot is too bright. So you'll have to turn it off. Luckily the 5x provide a very limited field of view. Therefore, if you adjust the alignment so that the red/green dot is exactly in the center of the field-of-view (FOV), then you can just use the monocular and the red dot scope without turning on the red/green dot.
In practice, I have not had a chance to take it on an outdoor MilSim night operation yet. But I can't wait to do so.
The Night Detective Quest 5 (ND-Q5) Night Vision Monocular retails for about $180. That's not cheap. The possibility of BB damage to the front lens element is highly likely. Luckily, it's relatively easy to protect it.

The Night Detective Quest 5 (ND-Q5) Night Vision Monocular has a 52mm front lens thread, which is standard in the photography community. You can get a 52mm UV filter to screw onto the front. I happen to have numerous 58mm UV protection filters, so I used an 52mm-58mm step-up ring to make the combination work (see photo below).
The night vision monocular is sensitive to light, so in strong sunlight, the image intensifier can be damaged. Therefore you should use a lens cap on the front of the UV filter when you are not using the monocular on a night mission. A simple camera lens cap will do. The photo below shows a Canon lens cap attached to the front of the monocular.
