There's currently a petition to repeal the Hughes Amendment you may want to sign:
"The 1986 Hughes amendment (as part of the Firearm Owners Protection Act) is an unconstitutional ban that limits law abiding citizens from owning fully automatic weapons that were manufactured past May 19, 1986. Select fire weapons are already very heavily regulated under the 1934 National Firearms Act which requires you to register your gun and submit a tax stamp. Since 1934 there have only been 2 known homicides committed with a legally owned fully automatic firearm and one of them was caused by a police officer. This law does nothing to prevent crime and it raises the price of legal automatic weapons to a ludicrous price due to supply and demand. Repealing the unconstitutional Hughes amendment will restore our second amendment rights that have been under attack for a very long time."
