Folisobo Adjustable 1.5-26mm Variable Diaphragm M30 to M37 Camera Lens Module Adaptor Rings for PVS-14 Night Vision

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

Works perfect for what I needed but only downside is there isn't a lens on the outside protecting the main lens of the NVG from dust and dirt but it is threaded for a lens

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

Just recently purchased my pvs 14 for November 13th... If you don't want to use your actual focus adjuster the adjustable aperture lens cap does the job.

This product does work well and with testing had no issues. The exterior adjustment side is not secure and needed a step up ring to make work.The exterior side is NOT 37mm but is actually 39mm. I purchased the 37mm and it was too small and would not screw in. I used a39mm-40.5mm step-up lense to secure the adjustment aperture for the iris. Saves a lot of money for the infinity focus when done properly.
