The gun guy rabbit hole is an embarrassing time suck and subculture.
Get good at one rifle, learn to shoot a pistol, carry every day, get a plate, build a belt, train, and always always treat it just like another tool and never a hobby to collect against and shoot the shit endlessly.
You can lose at life very quickly by becoming a gun guy and surrounding yourself with gun guys. Same goes for preppers and doomsdayers.
Life is scary and there are better strategies for coping with that reality.
Trust God.
