Clearly they are a corrupt and morally bankrupt organisation that enjoys funding from gun manufacturers:
"And the gun industry – led by Ruger – has benefited tremendously from the NRA. According to IRS fillings, from 2004 to 2010, the NRA’s revenue from fundraising — including gifts from gun makers who benefit from its political activism — grew twice as fast as its income from members’ dues. Over 50 firearms-related companies have given at least $14.8 million to NRA according to its list for a donor program that began in 2005. That was the year NRA lobbyists helped get a federal law passed that limits liability claims against gun makers."
