100 Years of Mossberg



It began in 1919 with a simple dream to manufacture durable and reliable firearms that the working class could afford. As simple as that dream was, it was fairly ambitious. After all, Oscar Frederick Mossberg, a Swedish immigrant, was 53 years old. But he was talented and determined. So armed with experience, innovative designs, and keen knowledge of the industry, he and his two sons, Harold and Iver, began O.F. Mossberg & Sons, Inc.

The First Mossberg


The Mossberg legend begins in a rented loft on State Street in New Haven, Connecticut, where Oscar Mossberg and his sons Iver and Harold begin producing the 4-shot, .22 caliber Brownie pistol. It would be the first in a long line of innovative, reliable firearms bearing the Mossberg name.


Mossberg offers up its first rifle, the MODEL K, a .22 hammerless pump repeater originally designed by Arthur Savage, then improved and finalized by Mossberg.

The Great Depression


The Mossberg legend begins in a rented loft on State Street in New Haven, Connecticut, where Oscar Mossberg and his sons Iver and Harold begin producing the 4-shot, .22 caliber Brownie pistol. It would be the first in a long line of innovative, reliable firearms bearing the Mossberg name.

The War Years


O.F. Mossberg and Sons wins a government contract to produce tolerance tooling gauges, .50-caliber machine gun parts, and components of the British Lee-Enfield rifle.

1941 - 1943

MODEL 42MB, a .22 training rifle created for British troops under the Lend-Lease Act.  Over 45,000 were produced.


Mossberg uses its entire advertising budget to get pre-draftees and junior shooters interested in rifle training. During this time, Mossberg produces several hundred thousand copies of the War-Department-endorsed Guidebook to Rifle Marksmanship.

Post War Era


The Model 183D bolt-action shotgun is introduced. It is the first Mossberg repeating shotgun and the first with an adjustable choke, features that would be found on many future Mossberg shotguns.


Mossberg releases the Model 400, the first in the line of Palomino lever-action shotguns. The Palomino line would stay in production for more than 20 years.


The first youth model, the 173Y, is introduced. This .410 bolt-action shotgun’s smaller stock opens up shooting to younger generations and smaller-statured shooters.

A New Era: The Mossberg 500

Mossberg 500


In August, the first Model 500 is produced. This pump-action shotgun would become legendary for its reliability and durability, and would lay the foundation for multiple variants to come.


Mossberg is awarded a government contract to produce the Model 500 as a combat-duty-rated pump shotgun. It will eventually be adopted by every branch of the United States Military.


With the discontinuation of the Model 395, Mossberg ceases production of bolt-action shotguns.


In collaboration with the Federal Cartridge Company, Mossberg releases its first shotguns chambered for 3.5-inch waterfowl magnum loads.


Mossberg spearheads the movement to include a safety cable lock with every new firearm. Developed by Alan Mossberg, the lock would eventually become standard for every manufacturer in the industry.
