I don't have ARs but we each have a 10/22, a brick house which we've kinda hardened with shatter proof storm doors and windows, roughly 12,000 rounds for the 10/22s and several extended magazines. We bought the good magazines from Ruger.
That will probably be sufficient
Many don't figure that unless you're
in the middle of a like minded
armed trained community, you're
not going to survive any firefights.
Police and military have the advantage
of calling for backup and relief.
Civilians are going to be pretty much
on their own, and all the looters/vandals/
home invaders have to do is to burn
you out or wait you out. After all this
antifa/blm type stuff, everybody should
be aware that the new breed will kill
just for the thrill of it and for spite.
It's not always a case of trying to get
your goods. If a bunch of invaders
try to breach your home space and
you kill one or two, you may as well
put your next one in your head because
they'll lay siege and cut you and any
loved ones up into spaghetti and it
likely won't be quick
If you're hiding out in the bushes down
in the creek bottom, you'll have a
50% chance they'll move along and
look for a well stocked place down the
road
