I dont know much about specific nightvision dedicated scopes as there is a reason we use clip ons. Other than not having to remove optics depending on if its day/night and rezero, the dedicated NV scopes generally do both ok but neither very well. If there is one that does, I'm betting its extremely cost prohibative.
Hell, you can barely get a decent non China scope for $600. Nightvision has to do with the generation of NV as well as the clarity the optic/NV unit has. Other than marks/spots/artifacts on the tube, using a cheap NV scope and/or a cheap day optic with a good clip on will make things look like someone smeared vasoline on a 7 up bottle and shined a flashlight through it.
Example; a PVS30 with a Nightforce or anything comparible is only 'good' up to maybe 12x where you start to really lose clarity and everything turns into a shimmering blob. The other problem you'll have is the further away the target at night, the more 'blob' like it will be as well as without legit IR illumination (and sometimes even with it) things get lost behind the smallest amount of cover or shadow; or you just know 'something' is there but don't know if its a person, dog, or a car. Meanwhile, PVS30 + nightforce + PEQ2a or PEQ15 and I'm down to, is that a coyote or a fox?
It all has limitations. I just can't see you getting anywhere near the distances you want with the budget you want to stay in.
