We always mounted a pvs 14 on our kpot and put a peq 15 on the rifle. They have good nv for rifles. Never mounted a pvs 14 on a rifle. Eotech has a pretty good system that sets up the pvs 14 behind their optic and now there is nv that will mount in front of an optic so you dont have to move your optic forward when switching to nv. Quality gear gets pricey though. Assuming you have the pvs 14 and dont want to shell out the dough for different nv if what you have will work?
You might be surprised at how many people out there own pvs14 and pvs7 units.I have no experience with a pvs14.. at that price point I most likely will not. I have found out that the chances of someone in the general public having a functional NV device outside law enforcement and the hog hunting community is very small. That being said possessing even a less expensive NV on even a 22lr is a massive game changer. Not knockin your choices ,I love the quality.
