Adjustable Iris Aperture Diaphragm M30 to M37 Iris Aperture Diaphragm Adapter Optical Diaphragm 1.5-26mm Lens Module Adapter Ring Optics PVS-14 PVS 14 Optics (M30/M37*1)

This is very good. Operates nice and smooth and it really does help with focus and if you don't have manual gain on your nv it would probably help a bunch. Finish is nice and it works well. Worth the price

PVS-14 PVS14 NODS NOD NVGS NVG yes it fits them. Does not close 100 percent so you’ll still need a cheap sacrificial lens but it’s a great set up. Not 5 stars cuz high price.

This is awesome for your PVS-14 and will allow you to adjust the focus on the go while providing protection to the lens in the 14. It is however going to need an additional sacrificial lens . I bought both on Amazon and this thing rocks and threads on easily! The sacrificial lens needed will thread onto the front of this will protect this iris clone! Also, your lens cover with pinholes will not fit over this iris but that's ok because if you buy this and and cover lens, you basically replicate the original covers. Just remember to remove the battery on your unit when it's in storage.

The media could not be loaded. If you want an aperture for your pvs 14 but don't want to spend the $250 then this is for you. Doesn't have sacrificial lens and maybe has some questionable build quality , but this works perfectly fine

Fits on both my PVS-14s and works great! Inifinite focus!Great cheaper alternative to name brandsNot the most rugged aperture made with a flimsy plastic but most optic accessories arent that rugged anyways

I didn't expect this one to hold up, but so far so good. Feels cheap but oh well

Works nice on my pvs14

Received the item but is not like what is displayed in the pictures or videos. Scam, don’t buy.
