AR-12 is kinda fun. A buddy has a cheapo and I've ran a few mags through it. More of a gimmick IMO. No clue on the reliability, but it's fun.
I mean a camera like a photo camera lol. I'm not that paranoid. Crime is really low here other than the meth heads and domestic violence.
I'm betting things will fall apart for everyone well before there are fascists outside my door. I'm more worried about the looters and the opportunistic ne'er-do-wells local to the area. Luckily I have a plan and property away from most people. It's not ideal, but it's better than being in a big city if SHTF. It's not something I think will happen, but better something than nothing.
