22 Secrets Mossberg Doesn't Want You to Know About the 500/590

In 1961, a self-taught engineer built a shotgun out of the "wrong" metal — and the whole industry laughed. Then the cheap aluminum gun outsold every shotgun ever made. Here's the part Mossberg's competitors would rather you never connect. This is the 500/590 story the gun-shop snobs never tell: 22 things hiding in plain sight on the most-produced shotgun in history. Inside the investigation: • Why the aluminum receiver everyone mocked is the smartest thing about the gun • The Remington patent that legally handcuffed a better gun until 1970 • The only pump shotgun the U.S. military ever certified — and it isn't the 870 • The world's first three-and-a-half-inch pump, built by the "budget" brand first • The tighter-pattern mystery two experts still can't fully explain • The 14-inch pump the government says isn't a shotgun 📄 FREE FIELD REFERENCE — the full 500/590 spec table, the sourced timeline, and the honest counter-evidence, on one page you can keep at the bench.
