Mossberg 590A1 12 Gauge 20" 6+1 Pump Shotgun - Tungsten Gray Cerakote Barrel, Magpul SGA Stock

The Mossberg 590A1 is the company's flagship 12-gauge pump-action shotgun, purpose-built to meet the most demanding military, law-enforcement, and home-defense standards. This Professional Series configuration (model 50797) carries Mossberg's heavy-walled barrel, metal trigger guard, and metal safety button - the rugged features that have made the 590A1 one of the most durable pump shotguns in production.

Chambered in 12 Gauge with a 3-inch chamber, this 590A1 pairs a 20-inch heavy-walled barrel with a 6+1 tube capacity for hard-hitting duty performance. The barrel and receiver are finished in a rugged Tungsten Gray Cerakote for corrosion resistance in punishing conditions, and the receiver is drilled and tapped for mounting optics or accessories.

This Professional Series variant is configured for shooters who prefer a tactical chassis. The smooth, ergonomic Magpul SGA synthetic stock in Black replaces the standard furniture, while a Magpul MOE forend provides confident pump manipulation under stress. Sighting is handled by Mossberg's proven Ghost-Ring rear sight paired with a front fiber-optic post for fast target acquisition in low light.

Pattern control is delivered through the proven Accu-Choke system, and this 590A1 ships with a Cylinder Bore choke installed so it is ready for buckshot or slug work straight out of the box. A clean-out magazine tube rounds out the duty-grade feature set. Proudly Made in the USA, the 590A1 is the standard-issue pump shotgun for U.S. military and law-enforcement users worldwide.
