What percent of NRA support is from sportspeople and target shooters, and what percent is from gun manufacturers?
I have bee an NRA member for many years and I believe it is mainly supported by member dues. It has a political lobbying group, the ILA, that sponsors state laws such as preemption to keep local cities from passing gun laws tougher than state laws. That too is supported by member donations. Firearm-related companies can donate to the NRA but also have an industry lobby group that they finance to keep the feds and states like NJ from passing laws against guns or gun parts. Member money is the biggest part of NRA income.
