The National Rifle Association of America (NRA) is a gun rights advocacy group based in the United States. Founded in 1871 to advance rifle marksmanship, the modern NRA has become a prominent gun rights lobbying organization while continuing to teach firearm safety and competency. The organization also publishes several magazines and sponsors competitive marksmanship events. According to the NRA, it had nearly 5 million members as of December 2018, though that figure has not been independently confirmed.

Gun safety is the study and practice of using, transporting, storing and disposing of firearms and ammunition, including the training of gun users, the design of weapons, and formal and informal regulation of gun production, distribution, and usage, for the purpose of avoiding unintentional injury, illness, or death. This includes mishaps like accidental discharge, negligent discharge, and firearm malfunctions, as well as secondary risks like hearing loss, lead poisoning from bullets, and pollution from other hazardous materials in propellants and cartridges. There were 47,000 unintentional firearm deaths worldwide in 2013.
