The Mossberg 590S Compact establishes a benchmark for pump-action shotgun utility, specifically engineered to cycle 1.75″, 2.75″, and 3″ shotshells interchangeably without requiring a dedicated mini-shell adapter. This design feature permits operators to select a specific shell length for an intended application or to integrate a combination of various shell lengths into a single loadout, optimizing operational adaptability and mission profiles.
Key Features
Shell Versatility
The core engineering advancement of the 590S platform is its ability to reliably cycle 1.75″, 2.75″, and 3″ shotshells directly from the magazine tube. This capability eliminates the need for aftermarket adapters, streamlining ammunition selection and reducing potential points of failure. Users can load any combination of these lengths, providing flexible payload management for diverse scenarios.
Receiver Integration
The receiver is factory drilled and tapped, facilitating direct mounting of optics or accessory rails. This enables robust attachment solutions for red dot sights, magnified optics, or other sighting systems, enhancing target acquisition and precision across varied engagement distances.
Ergonomics & Durability
Constructed with a durable synthetic stock, the 590S Compact is designed for consistent performance in challenging environments. The ergonomic profile ensures positive weapon manipulation and control, even under high-stress conditions. The pump-action mechanism provides proven reliability and a direct manual control interface.
