The NRA is non-partisan and has endorsed both [[Republican Party|Republicans]] and [[Democratic Party|Democrats]]. It most often endorses Republicans, as that party is more prone to fielding candidates receptive to Second Amendment rights.
In 2004 the NRA successfully opposed renewal of the federal assault weapons ban of 1994, which banned many features of certain semiautomatic rifles and certain types of removable magazines, against a campaign to make the ban permanent and expand it.<ref>http://www.nra.org/Article.aspx?id=886</ref> The ban expired at midnight, September 13, 2004.{{fact}}
The NRA owns and operates the National Firearms Museum in Fairfax, Virginia, which is free to the public.
