If I had to defend life and liberty short term, I’d go gas gun. There’s probably a half a dozen nuclear physicists or what not here that have argued for piston, old school $h!t stomper, whatever. Point Blank a shotty or CZ 75 please, longer range AR platform, extended range indefinite Pre-64 in a readily available cartridge, survival forever/no enemies a simple 452 Scout with slow target ammo.
