Which organization works specifically to support Second Amendment rights?

The National Rifle Association (NRA) is dedicated to advocating for Second Amendment rights, which pertain to the right of individuals to keep and bear arms. This organization actively engages in various activities, including lobbying for pro-gun legislation, providing firearms training to the public, and promoting the significance of the Second Amendment in American society. The NRA's mission aligns closely with protecting and promoting gun ownership rights, making it the organization most specifically focused on supporting Second Amendment rights.

In contrast, the Human Rights Campaign primarily focuses on LGBTQ+ rights; the ACLU works broadly on civil liberties issues, including free speech and privacy rights, but does not focus exclusively on gun rights; and the NAACP is centered on advancing civil rights for African Americans and promoting social justice. These organizations do not have a primary or specific emphasis on Second Amendment rights, which further highlights why the NRA is the correct choice.
