If you bought your "assault rifle" during one of the last "assault weapons bans" and paid way too much for it...yes, now would be a good time to get back some of that money and buy lots of other stuff with it. Or like bilmac says, if your not happy with something, yes now is a real good time to cash in. I would not worry about what the government bans...last ban did not outlaw anything we already had, or keep us from selling them or using them, and even if the next one does none of us have any of those.
Obama just put thousands of AR's in the public by talking about it, big sales still going strong, there are going to be a lot of assault weapons to choose from. There will be more AR's than Winchester 94's in the private sector.
If my state were talking about this...I would not give anything up I did not want to....I also hope someone sees this as unconstitutional besides us.
