The NRA Political Victory Fund (NRA-PVF) is NRA's political action committee. The NRA-PVF ranks political candidates - irrespective of party affiliation - based on voting records, public statements and their responses to an NRA-PVF questionnaire.

NRA relies on a very simple premise: when provided with the facts, the nation's elected officials will recognize that "gun control" schemes are an infringement on the Second Amendment and a proven failure in fighting crime. The importance of this premise lies in the knowledge that, as one U.S. Congressman put it: "The gun lobby is people."
