While widely recognized today as a major political force and as America’s foremost defender of Second Amendment rights, the NRA has, since its inception, been the premier firearms education organization in the world.
Some history of the NRA can also be found on this Wikipedia page:
The National Rifle Association of America (NRA) is an American nonprofit organization that advocates for gun rights.
Founded in 1871, the group has informed its members about firearm-related bills since 1934, and it has directly lobbied for and against legislation since 1975. It has been called the oldest continuously operating civil rights organization and the “largest and best-funded lobbying organization in the United States”.
From the NRA’s website:
The NRA is America’s preeminent gun rights organization, made up of nearly five million members. Together, we fight and win the toughest battles for the Second Amendment, all while offering the best firearms educational programs in the country.
