A Brief History of the Mossberg 500
O.F. Mossberg & Sons introduced the Mossberg 500 in 1961 as an affordable, no-nonsense pump-action shotgun. The company, founded in 1919 by Swedish immigrant Oscar Mossberg, had built a reputation for making reliable and budget-friendly firearms. The Mossberg 500 was designed to be simple, durable, and accessible to everyday shooters.
Over the years, the Mossberg 500 evolved into a true modular shooting system. Interchangeable barrels allowed one receiver to serve multiple purposes — from bird hunting to deer hunting to home protection. The addition of dual action bars improved smoothness and reliability. The platform even proved its toughness by passing strict military testing standards, cementing its reputation as a workhorse shotgun.
Today, the Mossberg 500 remains in full production with modern updates including synthetic stocks, tactical configurations, classic Retrograde models with walnut furniture, and the innovative FLEX system that lets users swap stocks and barrels in seconds without tools.
