Actually, the NRA is NOT a 501(C)3 organization....

From the NRA website:

Established in 1990, The NRA Foundation, Inc. ("NRA Foundation") is a 501(c)(3) tax-exempt organization that raises tax-deductible contributions in support of a wide range of firearm-related public interest activities of the National Rifle Association of America and other organizations that defend and foster the Second Amendment rights of all law-abiding Americans.

The Foundation & the NRA being two separate legal entities i.e. slightly different way of going about it but same basic result.
