The final touch on my 10/22 post SHTF gun would be a 2-7x28mm compact model Leupold scope on QD rings........this scope is very tough but I can dump the scope in seconds if it breaks & use the iron sights.
The scope will double as my reconnaissance field optic........in a post SHTF world you'll likely need to destroy a lot of your incidentally observed live critters either for food &/or protection.......whether they're on 2 or 4 legs won't matter after a while.
After the complete collapse has been reality for a while and the nut cases know for sure they are free agents answerable to no one an armed human I don't know will be neutralized instantly & without hesitation.
We didn't make
number 1 on the worlds most dangerous predator list by being Mr. Nice Guys...........you'll be mortified at what's left after the thin veneer of civilization washes off of us all........no exceptions..........the DNA blueprint is basically the same.
Like "The Governor" in "The Walking Dead" TV series says..........
YOU KILL OR YOU DIE !
