O.F. Mossberg & Sons

The Mossberg 500 is a pump‑action, 12‑gauge shotgun introduced in 1964 that embodies O.F. Mossberg & Sons' philosophy of rugged simplicity, affordability, and modularity for civilian, law‑enforcement and limited military use. Its hallmark is a dual‑action, steel‑reinforced receiver with a patented “anti‑jam” bolt and a simple, interchangeable barrel system that allows rapid conversion between 12‑gauge, 20‑gauge, and .410 bore configurations. The shotgun’s ambidextrous safety lever, low‑profile stock, and easy‑to‑clean design have earned it a reputation for reliability in harsh environments, making it a staple among hunters, home‑defense owners, and tactical units. Distinguishing features include the “Mossberg choke” system, a free‑floating barrel, and a takedown design that requires no tools, which together contribute to its enduring popularity and status as one of the best‑selling shotguns in the world.

The Mossberg 590 is a rugged, pump‑action shotgun engineered for reliability in demanding law‑enforcement, military, and civilian environments. Originating from O.F. Mossberg & Sons' long tradition of utilitarian design, the 590 emphasizes a simple, low‑maintenance action, a steel receiver, and a synthetic stock that resists corrosion and harsh weather. Its primary purpose is tactical and defensive use, with a focus on rapid follow‑up shots, high ammunition capacity, and ease of field stripping. Distinguishing features include a dual‑action safety/trigger lever, a robust chrome‑lined barrel, and interchangeable barrel lengths ranging from 14 to 20 inches. The shotgun’s reputation rests on its durability, affordability, and the ability to accept a wide variety of aftermarket accessories, making it a staple among U.S. police departments, SWAT teams, and civilian home‑defense owners. Unique to the 590 line is the “tactical” configuration with a pistol grip, ghost‑ring rear sight, and a high‑capacity tube magazine, which together provide a blend of shotgun firepower and rifle‑like ergonomics rarely seen in pump‑action platforms.

The Mossberg 590A1 is a heavy-barreled 12-gauge pump-action shotgun that is the only shotgun to meet and pass the stringent U.S. military MIL-S-3443G specification for combat shotguns. It features a thicker-walled barrel than the standard Mossberg 500, a metal trigger guard and safety button instead of polymer components, and a bayonet lug that accommodates the standard M16 bayonet. The 590A1's renowned durability, combined with its ambidextrous tang-mounted safety and dual extractors, has made it a preferred choice for military and law enforcement units since its adoption by the U.S. Navy and Marine Corps in the late 1980s.

The Mossberg 500 ATP (All Terrain Pump) is a specialized variant of the Mossberg 500 shotgun with a corrosion-resistant parkerized finish and synthetic stock. It was designed for military and law enforcement use in harsh environments. The ATP features a 20-inch barrel, 6+1 capacity, and ghost ring sights.

The Mossberg 590 Shockwave is a uniquely classified 12-gauge pump-action firearm with a 14-inch barrel and a distinctive birds-head pistol grip that allows it to be legally sold as a non-NFA firearm under United States federal law. Because it is manufactured without a shoulder stock and has an overall length of 26.37 inches, the Shockwave falls into a regulatory category of 'firearm' rather than 'short-barreled shotgun,' making it accessible without the tax stamp and registration required for conventional short shotguns. The Raptor birds-head grip and forward strap provide positive control during one-handed and two-handed operation, and the Shockwave has become one of the best-selling firearms in its category for home defense and vehicle carry.

The Mossberg 835 Ulti-Mag is a pump-action shotgun chambered for 3.5-inch magnum 12 gauge shells, introduced in 1988.

Designed for waterfowl and turkey hunting, it was among the first production shotguns to chamber the 3.5-inch shell.
