Key Features
Robust Action System
The core of the 590’s operational integrity resides in its robust action system. Dual extractors facilitate consistent spent shell removal, while the positive steel-to-steel lockup ensures secure breech closure under various conditions. Twin action bars distribute operating forces evenly, mitigating binding and promoting smooth cycling. An integrated anti-jam elevator mechanism further optimizes feed reliability, ensuring uninterrupted operation when precision and speed are paramount.
FLEX Modular System
The Mossberg FLEX system integrates tool-less interchangeability for primary components. This design allows rapid adaptation of the stock and forend to specific operational requirements or shooter preferences, enhancing the platform’s versatility without requiring specialized tools. This modularity streamlines maintenance and configuration adjustments in the field.
Optimized Ergonomics
Equipped with a 6-position adjustable synthetic stock, the 590 FLEX Tactical allows operators to precisely tailor the length of pull for optimal control and fit, whether utilizing body armor or adjusting for different shooting stances. This ergonomic design optimizes weapon manipulation and reduces fatigue during sustained use, contributing to enhanced shooter interface and control.
Durable Construction
Constructed to withstand harsh operational parameters, the 590 FLEX Tactical features a durable receiver and barrel, engineered for longevity and consistent performance. The protective finish is designed to resist environmental degradation and minimize reflective signature, ensuring sustained operational integrity in diverse conditions.
