I thought about a possible night vision scope but not sure how that would work, may be better to have a night vision spotting monocular then switch to the rifle with laser -light. I think you could literally pick up enough 'coons, passums and rabbits patrolling a few square miles to stay healthy for a while.
This sounds a little "ninja-esque" for me, but if you've done enough research to justify spending the cash on NVG that would work with this setup, I'm curious as to why you're asking us for advice. That, and the "light and lazer" gimmicks that I've seen can be some serious junk that just attract attention.
It is important that this rifle fold and fit in a backpack so I just look like I'm walking home.
Walking home from what? School? A Job? If it's a real SHTF type thing which you're asking about, and your point is to get away from people....what are you walking home from, and why would you be so concerned about what these other people (that you're some distance away from) think?
Just buy a good Single-Six, and practice practice practice at distance; if you absolutely, positively have to hide it, it's doable. As for the rifle option....possibly a
Marlin 39A, since they can be "taken down" (not sure how good of an idea that is for a backpack, though), though it has a longer barrel--but they're accurate. Or, the
Marlin 925 series seems to be accurate. Neither rifle is in stainless, but maintenance wouldn't seem to be too hard on a bolt-action .22.
Or, get a stainless 10/22, and slick it out with the latest and greatest plastic folder.
