Some people, who are worried about confiscation, are diversifying into the "cowboy assault rifles", the lever action 30-30s and such, to hope to avoid being on the "list". It'll work, for a while - Teddy Kennedy said 30-30 is an armor piercing round, and should be banned.
I'd say get what you can, off books if legal in your state, and don't let the farging iceholes ruin your life. But, your primary goal should be to work your tail off fighting anything coming down the political pike, join the NRA, GOA, etc., and do your part to, A) make the next four years survivable, and B) make sure it's ONLY four years!
