You can always count on Montana to lead the fight on gun rights. Keep in mind that was introduced by Jon Tester in September of last year. It seems absent from his website now. This site would seem to indicate nothing happened with it.
There are two thing that were mentioned that I did not know about that I will research further
*** New BATFE regulations on semi-automatic rifles, requiring firearms dealers to act as an informant to anti-gun federal bureaucrats if someone buys more than one rifle;
*** The Disarming American Citizens Act (H.R. 2159 in the last Congress) letting Attorney General Eric Holder revoke the Second Amendment rights of ANY American he chooses based on pure suspicion
