Engineered for rugged reliability and smooth operation, the 590 Tactical combines Mossberg’s legendary durability with modern ergonomic upgrades including the versatile FLEX stock system and interchangeable pistol grip configuration.

Combined with twin action bars and steel-to-steel lockup, the shotgun delivers dependable pump-action reliability under demanding conditions.
Further enhancing reliability are the shotgun’s rugged dual extractors, which provide positive shell extraction and improved cycling performance even during heavy use. The durable design helps ensure consistent operation with a wide variety of 12 gauge loads.
Built with a durable 20" barrel and chambered for powerful 3" 12 Gauge shells, the Mossberg 590 Tactical delivers formidable defensive capability while maintaining manageable handling characteristics. The adjustable stock, bead sight system, and 8+1 capacity make it exceptionally well-suited for home defense, security use, and tactical training.
