O.F. Mossberg & Sons (commonly known as Mossberg) is an American firearms manufacturer, specializing in shotguns, rifles, scopes, and firearm accessories. Thanks to the Brownie pistol, the Mossbergs’ firearms business grew steadily, and in 1921 the company purchased a building on Greene Street in New Haven, Connecticut. In 1922, the company introduced the first of a new line of .22 rimfire Mossberg rifles, a pump-action repeater designed by Arthur E. Savage, the son of the owner of Savage Arms Corp.
