In 1886, Oscar Frederick Mossberg emigrated from Sweden and began work at the Iver Johnson Arms & Cycle Works in Fitchburg, Massachusetts. In 1919, he and his two sons, Harold and Iver, began O.F. Mossberg & Sons, Inc. with a dream to build durable, reliable firearms. The Mossberg legend begins in a rented loft on State Street in New Haven, Connecticut where Oscar Mossberg and his sons begin producing the 4-shot, .22 caliber Brownie pistol. Mossberg made approximately 37,000 Brownie pistols.

In 1947, the Model 183D bolt-action shotgun was introduced. It was the first Mossberg repeating shotgun with an adjustable choke.

In August 1962, the first Model 500 was produced. This pump-action shotgun would become legendary for its reliability and durability, and in 1979 Mossberg was awarded a government contract to build the Model 500 as a combat-duty-rated pump shotgun. Every branch of the United States Military would eventually adopt it.

In 2017, the revolutionary Mossberg 590 Shockwave was introduced. This ultra-portable shotgun gave shooters a legal alternative to a short-barreled shotgun without needing a tax stamp.

2019 – Mossberg celebrates 100 years in business. The company has remained family-owned, family-operated, and committed to offering “more gun for the money” with the most innovative, reliable firearms on the market.


Mossberg debuted its 940 Pro Tactical model at the 2023 SHOT Show. The 940 series features a durable gas system that allows up to 1500 rounds between cleanings, a host of corrosion-resistant internal parts/finishes, an enlarged loading port, an elongated elevator, and an anodized follower for smooth operation. Outside, an adjustable stock allows for length of pull adjustability with included spacers, and the 940 Pro Tactical comes drilled and tapped, optic-ready with receiver cuts that accept low-profile direct mounting of Shield RMSc-pattern micro dot sights— for improved eye alignment and target acquisition. Also available with a Micro Dot.

The 940 Tactical barrel is 18.5 inches long, with a blued steel finish and a fiber optic sight front sight. It comes with a barrel clamp equipped with M-LOK mounting slots for slings and accessories.
