What does everyone use to help with target acquisition in low light situations? I'm specifically looking for things like night sights as opposed to night vision.
The Russians and former Soviets have a wide variety of mil spec NV optics. Some of them are huge 80's era Gen 1 and Gen 2 models but there are a few new monocular style Gen 2+ on the market that are naturally much smaller. PN16K and PN21K come to mind.
There are a few Gen 1 civilian NV optics out there too so it depends on what you want Russian wise and what you're intended use is.
All this assumes your rifle has a side rail of course and if it does you can use a weaver or picattinny mount and use many kinds of Western optics as well. If it doesn't you can try the TWS rail or similar.
Example of PN16K with Rakurs-PM. Both are mounted on the NPZ side mount which is long enough to mount a wide variety of optics.
Personally I don't do much night shooting but I still really love the big honking 1PN34 and 1PN58. If SHTF I might be using something a little lighter of course.
