Mossberg shotguns are primarily manufactured in Eagle Pass, Texas.
Production and Headquarters
While O.F. Mossberg & Sons, the oldest family-owned firearms manufacturer in America, maintains its corporate headquarters in North Haven, Connecticut, nearly all of the company's firearms production, including their popular shotguns, has been consolidated to their facility located in Eagle Pass, Texas. This strategic move has shifted the vast majority of Mossberg firearm manufacturing operations to the Texas plant.
