I fail to see the good news. Any ban on any legally obtained firearm in America is a loss for all ........period. No ifs, ands or buts. What we have to defeat is the anti-gun movement's power, and not allow it to gain momentum. If they succeed in banning any type of now legal firearms that are in the hands of American citizens the snowball will have begun to roll downhill. It's always much easier to keep something from moving than it is to stop it once it does.
Work NOW! Don't be sorry later that you didn't. A defeat for them now will take some wind out of their sail.
