New Haven 600 is a series of pump-action shotguns manufactured by O.F. Mossberg & Sons on behalf of department stores, most notably the Montgomery Ward Company, Western Auto, and other retail stores. New Haven is one of O.F. Mossberg & Sons' private, promotional brands. The New Haven 600 is identical to the Mossberg 500 from O.F. Mossberg & Sons, with the addition of an anti-rattle system in the magazine tube. The 600 series comprises widely varying models of hammerless, pump action repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, and "furniture" (stock and forearm) materials.
