The Mossberg 590S Tactical is a 12 Gauge pump-action shotgun engineered for reliability and adaptability under demanding conditions. Its primary distinction is a robust feeding system designed to cycle 1.75-inch, 2.75-inch, or 3-inch shotgun shells interchangeably from the magazine tube without requiring an adapter. This inherent versatility simplifies ammunition management and broadens its utility across diverse applications, from field use to operational deployment.
