FYI I have found it much easier and more consistent to put the electrical tape on the inside of the Butler Creek just to add some friction. Instead of taping the NVG

[@Gooberz710]

How you managed to get electrical tape even cut in half inside of the cap with the aperture is beyond me. Please make a video showing how you did this because I want to still be able to adjust my objective lens and not have it taped over…

[@Iwillsurvive115]

Just a question what nvg is this what brand ?

[@darth_1]

Fun fact if you buy the m32 m37 Iris it just twist no need for the lever and the Butler Creek cap fits directly over that with no tape. No dremel work needed

RIT liquid graphite dye does a good job on the red lever.

[@anthonyreddy2834]

I had no idea what the heck you were doing till the end😳 Nice! Job!

[@spammyoliveolive8507]

This is great! I'm planning on doing something similar with my new PVS-14 now, thanks a ton!

[@richardzapata357]

I just did this today, thanks to your video. I’m about to test it out here pretty soon. Thanks a lot!

[@Dilly_franks]

Awesome timing man I have some showing up Monday, thanks for the vid!

[@thomassferes8487]

Great job! If I can offer on a tutorial video would be to slow down!! please, I needed a drink afterwards. But I will try again many thanks!!

[@williamklaproth85]

I just bought an iris that threads on.

[@friedchickenandwatermelon8307]

Hey man, could you please elaborate more on which kriss you bought and size? Was it for a pvs 14? Thanks man.

[@carlh4350]

I wonder if you could glue the adjustable iris to the flip up lid? That way you could flip it out of the way when you need full light. The adjustable iris looks a little smaller than the full pvs14 lense. I bought the parts you linked, when they get here I'm gonna look at it. Thanks for the video

[@mpireoutdoors5274]

Lovely. Would be interesting to see a similar option with an epoxy magnifying lens. Don't get the stuff on your skin though and don't breathe the fumes - stir in a place with lots of airflow and a particle mask.

[@simply_based]

Here from reddit, nice work

[@Gooberz710]

Definitely want to use callipers or be exact on where you’re cutting it especially if you end up using a sacrificial lens in front of the aperture instead of one of the screw in sacrificial lens behind the aperture. Figured the objective lens would be sealed off from the elements and dust/debris a bit better with a screw on sacrificial lens behind the aperture. Already ordered some more butler creek caps because I botched the fuck out of the first one though. So just be careful. I know the flip cap is only $8.99 on some sites, but still sucks to not have an extra in case you fuck up…. PS they’re constantly going out of stock and went from $9 to $13 and some change on Amazon haha wonder why

[@TheDE4THangel]

Sweet video keep it up 🤙

[@SavageRonin191]

Dude so awesome... Thanks for your help

[@theguess7]

Thank you. This is great.

[@berkharbin6642]

Really cool.

[@Rocketrich88]

Dude, Awesome Video… What tubes do you have?

[@GB-uu1yd]

Nice DIY solution. I'd be hesitant ussing it in rain though. Seems like you could get water buildup in the lens cap.

[@epapa737]

You could probably water seal it if you really wanted

[@julian23561]

Looking these up, so help me out here gents: these are basically aperture devices that allow you to have a shorter length of focus and therefore allow you to see much clearer with nightvision on, correct?

[@snake6221]

One year later: Correct, lol. Clearer at short distances.

[@nikkobrown421]

Sucks you'll be giving up slight light transmission no matter what, I wanna see a version where the actual iris flips up so you gain the entire objective lense, with your mod even the mat block tarsiers you lose like almost a quarter inch of the outer edge of the objective lense, while some might say who cares, that might make or break you seeing something in a no ambient light place , gonna need all the gain you can get

[@berkharbin6642]

You could probably modify it to mount the iris in the flip cap with a little 3D printing.

[@3o5wasabii]

[@Ejinikus]

Take it off if it gets that dark?

[@WebflingerJoe]

Buddy of mine hacked his finger halfway off with one of them little zipdiscs, be careful dude. Wear some cheap goatskin gloves lol.

[@brandonbooth3702]

Damn, 1 month to ship that iris.

[@carlh4350]

Does this reduce the overall lense size enough to lower the light gathering and fov on the pvs14? It doesn't look like the iris opens up to the full size of the pvs14 lense.

[@LarpingSupply]

Correct but it’s negligible and easily reversed by simply removing them

[@votago]

I was looking at some gentleman’s Instagram. He offers this thing for $95. Doesn’t include the adjustable iris. Fucken you here showing how to make one for $50 with shit from Amazon lol. Thank you

[@LarpingSupply]

No but someone on Reddit walked me through this.

Do not use a qtip on any lenses. They can scratch lenses pretty easily, they even scratched my ACOG's lens.
