Mossberg 590 FLEX Tactical 12 Gauge 8+1 20" Barrel Adjustable Stock

The Mossberg 590 FLEX Tactical delivers adaptable firepower with its innovative modular design system. This 12-gauge platform combines proven reliability with customizable configuration options for multiple tactical applications. The FLEX system allows rapid reconfiguration between different mission profiles without tools.

What Makes This Different

The FLEX Locking System sets this shotgun apart from traditional fixed-stock models by enabling quick changes between six different length-of-pull positions. While standard tactical shotguns require permanent modifications for fit adjustments, the 590 FLEX adapts instantly to different users or gear configurations. The dual extractors provide enhanced reliability compared to single-extractor designs, reducing potential extraction failures under adverse conditions.

• FLEX Locking System with 6-position adjustable stock (12" to 14" length of pull)
• 20-inch barrel with cylinder bore optimized for tactical loads
• 8+1 capacity with 3-inch chamber capability
• Dual extractors for enhanced reliability and positive case extraction

Field performance demonstrates consistent cycling with various load types from 2¾-inch target loads to 3-inch magnum shells. The 20-inch barrel length balances maneuverability with velocity retention, making it suitable for home defense, law enforcement patrol, and competitive shooting applications. The anti-jam elevator and positive steel-to-steel lockup maintain function in dusty or wet conditions.
