The GOA is an adamant enemy of gun control measures of all stripes, and proudly calls itself the “no compromise” gun lobby. Its surge in lobbying spending reflects one way it has capitalized on the financial and legal problems of the once 5 million-member NRA in the hopes of expanding the GOA’s political clout, say gun experts.

“The GOA was formed in the 1970s because they believed the NRA was too liberal,” said Robert Spitzer, the author of several books on guns and a professor emeritus at Suny Cortland in New York. “True to its creed, the GOA has opposed every manner of gun law and attacked the NRA at every turn.”
