This is really all the firearms you need. I do think it’s important to finish the kit. You should eventually have a chest rig + plates, a go bag that is ready for a 3 day trek, a small stockpile of ammunition, a ballistic helmet, and some form of night vision.

As for night vision, I think the cheap digital versions should be avoided. Absolute cheapest NVG you should buy in my opinion is a single tube PVS-14, around $4,000. The issue with night vision is that the new thermal hybrid night vision is basically unstoppable. You basically can’t hide from it. You can get pretty good thermal hybrids (overlays the thermal image over the top of the analog night vision) for not much more than a dual tube PVS-14 setup.

Something like the Arkayne RENV-B is around $9,000-12,000 depending on which image intensifier tubes you choose. It’s a dual tube night vision with a thermal imager attached to one of the tubes. It overlays the thermal image over the night vision. So the thermal view has a bit of a latency, unlike the analog night vision, but it’s worth it.

It may be tough to justify spending that much on night vision you will probably never use unless you take it hunting, but with thermal night vision, you become a hyperpredator. You become like a mage in elder scrolls using detect life
