Mossberg 590 12 Gauge Shotgun 20" Barrel 8+1 M-LOK Ghost Ring

The Mossberg 590 delivers proven tactical performance with modern enhancements that address the demands of serious shooters. This 12-gauge platform combines the reliability of Mossberg's dual extractors with contemporary features like M-LOK compatibility and precision ghost ring sights.

What Makes This Different

While standard pump shotguns rely on basic furniture and iron sights, the 590 integrates M-LOK mounting points directly into the forend for tactical accessories. The ghost ring sight system provides faster target acquisition than traditional bead sights, with a larger sight picture that maintains precision at extended ranges. The cylinder bore barrel handles everything from buckshot to slugs without choke restrictions.

Key Features

• 20-inch cylinder bore barrel optimized for tactical loads and slugs
• 8+1 capacity with 3-inch chamber capability for maximum versatility
• M-LOK compatible forend accepts lights, grips, and other accessories
• Ghost ring sights with windage-adjustable rear for precise shot placement
• Dual extractors and positive steel-to-steel lockup ensure reliable cycling
• Black synthetic stock resists weather and impacts better than wood
• Tang-mounted safety accessible to both right and left-handed shooters

Field testing demonstrates consistent cycling with 2¾-inch and 3-inch shells across various manufacturers and load types. The 20-inch barrel length balances maneuverability with ballistic performance, making it suitable for home defense, tactical applications, and hunting scenarios. The synthetic furniture maintains zero shift in temperature extremes from -20°F to 140°F.
