I understand the magazine ban has been slapped down for now.
Some things some people might do that make sense:
- Keep one full up, fully featured non-Cali-legal AR15 zeroed w/ reliable optic cached.
- Keep one Cali legal in your house for minor training.
- Go to neighboring states for serious carbine classes and rent their rifle.
- Buy ammo in neighboring states and cache it w/ cache rifle. (Ammo that is EXCELLENT for caching is this
http://www.sgammo.com/product/223-556mm-ammo/1000-round-case-223-rem-56-grain-fmj-golden-tiger-steel-case-ammo-made-vympe-0 .....this is the new production batch where you DONT have to upgrade your firing pin/hammer spring for a hard primer.. accurate, laquered, bullet neck and primer nicely sealed a la russian mil spec. )
This way you can train and keep some minor combat power in your house.. but when there is a power outage and the orcs are killing everyone for food/water you get your cache rifle and are ready-to-go.
Also may not hurt to keep some spare jerry cans around while you're at it if you live in a densely populated area ( I do)
