Review: Perfect for a PVS14 - I recently installed this adjustable iris on my PVS-14, and I have to say, I’m seriously impressed with its performance. It works flawlessly, allowing me to quickly and easily adjust the amount of light coming through, which is crucial in varying conditions. The smooth adjustment mechanism feels solid and reliable, and it has a precision that rivals—and even outperforms—some of the more well-known models that cost five times as much. What really stands out to me is how well-built this iris is. Despite the lower price tag, it doesn’t compromise on quality. It locks securely in place and doesn’t feel flimsy or cheap in any way. I’ve used higher-end versions before, but this one really surprised me by how well it holds up. If you’re looking for a great, affordable upgrade for your PVS-14, this adjustable iris is an absolute steal! You won’t miss the expensive models at all.

### ⭐⭐⭐⭐⭐ Works exactly as advertised
*by R***D on May 5, 2024*

Works similar to a manual gain where it can lower the light intake and dim the image. The smaller the aperture hole, the more crisp the image through the tubes. Allows for images near and far to be in focus simultaneously the smaller the aperture hole. Can clearly focus in on objects 100 meters away and my watch at the same time. Great product.
