$1000 is not enough to really do much ... maybe buy $500 worth of ammo, a couple of AR lowers, and some AR mags. I think that ammo will be taxed so high that it will no longer be affordable.

and the word from the Obama's own website

Address Gun Violence in Cities: As president, Barack Obama would repeal the Tiahrt Amendment, which restricts the ability of local law enforcement to access important gun trace information, and give police officers across the nation the tools they need to solve gun crimes and fight the illegal arms trade. Obama also favors commonsense measures that respect the Second Amendment rights of gun owners, while keeping guns away from children and from criminals who shouldn't have them. He supports closing the gun show loophole and making guns in this country childproof. He also supports making the expired federal Assault Weapons Ban permanent, as such weapons belong on foreign battlefields and not on our streets.
