If we do have a social meltdown, it will be AMMO that will be in short supply, not so much guns themselves.
For the same $10,000 family investment, ten AR's ($7,500) and 1,250 rounds ($2,500) of ammo is of far less utility than two AR's ($1,500) and 42,500 rounds ($8,500) if there truly is a meltdown. Or if you have kids, maybe four AR's ($3,000) and 35,000 rounds ($7,000).
Unfortunately possessing that much ammo could get a person in trouble many places. I usually have 3,000 or so rounds, because we all shoot alot, and even that much raises eyebrows from some quarters.
Even most of who are AR junkies are probably more in the $4,000 club if our family all shoots them, even if we have several AR's - four AR's and 4,000 rounds represent about $4,000 in money tied up in EBR's.
