George Washington ordered the creation of the Springfield Armory in 1777 to store revolutionary ammunition and gun carriages. In 1794, the armory began the manufacturing of muskets for the young country.

For the next 150 years, Springfield Armory functioned as a supplier for every major American conflict as well as a think-tank for new firearms concepts. In 1968, citing budgetary concerns, the US Government closed the armory. In 1974, the passionate Reese family rescued not only the name Springfield Armory, but the philosophy that drove it for centuries.

With reverence for the legacy of the armory, the Reese family resurrected the mostly historically significant designs produced by the armory - the M1 Garand, the 1911, and the M14. Fueled by the same obsession for improved manufacturing techniques and cutting edge design that inspired the likes of John C. Garand, they've continued to develop products that are loyal to Springfield's® heritage while ensuring the armory's place in the progression of American firearms.
