Boy did this thread go to hell fast... but then made a nice recovery. I do not like mudslinging, but not that we are back to civilized discourse, I figured I should chime in again.
My original recommendation of Vortex Razor Gen 3 and S&B Dual CC, generally stands, but the S&B is designed to work on 1x with a battery. It works really well, but I would have liked some reticle features that give it usability if push comes to shove without a battery (and gave that feedback to S&B). Here is what it looks like on 1x with the illumination on and off:
Interestingly, at close range, I can comfortably get quick center of mass hits without the reticle being there at all, but that starts getting iffy (for me), past 25 yards or so.
Vortex Razor Gen3 1-10x24 has non-illuminated reticle features that work on 1x. It is no an ideal arrangement, but it is usable.
Here is what it looks like non-illuminated:
And illuminated, though not on full blast:
For a general purpose scope that goes to fairly high illumination, I do prefer FFP. In use, it is comforting to not care at all which magnification I am on.
Now, if you really want non-illuminated visibility on 1x, you kinda have to go with SFP and there Vortex Razor Gen2E 1-6x24 is very nice and very quick, as is the similar Delta Stryker 1-6x24 that is a little lighter. I think the SIg Tango6 1-6x24 is also a related design.
Here is a look through the Stryker 1-6x24:
That having been said, if this is an exercise in planning for a civilizational collapse and what will happen when you can no longer get batteries, you are probably thinking about it the wrong way.
Aside from the fact that you will have many other significantly more important problems than optics selection, you should really be thinking about redundancy. If this is really a plan for something apocalyptic, I would be buying and setting up multiple sighting systems. Everything made by man can and does break occasionally, so you better have backup.
By all means, get the nicest LPVO you can afford, but if also get something simple and durable for backup. For example, something simple like the SWFA SS 3-9x42 with an offset red dot will cost you a lot less money, have a proven track record of durability and provide some redundancy. And it will work better for hunting in low light owing to a large objective lens. You are far more likely to be foraging for food than fighting off hordes of zombies.
To be entirely honest, I am as paranoid as anyone else and I do have two of those SWFA 3-9x42 scopes set up with red dots exactly as I mentioned. I also have Razor Gen3 and S&B Dual CC. And the 1-6 Stryker. And a bunch of other stuff. Scopes come and go all the time. At any given time, I have between 30 and 60 different scopes and red dots here. New stuff gets here all the time and other stuff leaves. However, for every scopable rifle, I have a primary scope and a back up scope. It has nothing with coming apocalypse. I just like redundancy and consider it to be cheap insurance for some of life's quirks.
