A few years ago I was with my friends as we tested one of the PVS24s for possible use by the police sniper team. I ran across the pictures I took this morning. You can see it above compared to my PVS14.
I was surprised to find out that I prefer the clarity of my PVS14.

The 24 clips on in front of the regular day optic. It does not change the weapon’s zero.

It is long and there are other options for front mounting night vision that are smaller. Including FLIR. We thought this would be amazing but it was pretty meh. It was hard to see a human standing in plain sight at 100 yards and nearly impossible when one squatted down into waist high grass. A Surefire light with IR head helped a bit, but not much.
