Product Overview
The Mossberg 500 Flex Bantam Combo 20 Gauge Pump Action Shotgun represents a highly adaptable and robust firearm solution, engineered to meet diverse operational requirements. This system integrates Mossberg’s proven 500 pump action reliability with the innovative FLEX modular platform, allowing for rapid field configuration changes without tools. The “Bantam” designation indicates an optimized ergonomic profile, specifically a reduced length of pull, enhancing handling for shooters requiring a more compact fit. Supplied as a “Combo,” this package includes multiple barrel options, providing immediate versatility for both sporting and practical applications.
Key Features
FLEX Modular System
The core of this system is the Mossberg FLEX modular interface. This feature enables tool-less interchangeability of stocks, forends, and recoil pads. Operators can rapidly reconfigure the shotgun’s ergonomics and profile to adapt to specific scenarios, whether transitioning from a field setup to a more compact configuration, or tailoring the fit for different shooters. This system significantly expands the utility and adaptability of the platform.
20 Gauge Versatility
Chambered in 20 gauge, this shotgun delivers a practical balance of power and manageable recoil. The 20 gauge offers sufficient ballistic performance for a wide array of applications, including hunting upland game, waterfowl, and deer (with appropriate ammunition), as well as home defense scenarios. The reduced recoil impulse compared to 12 gauge further mitigates shooter fatigue during extended sessions and improves follow-up shot acquisition.
Bantam Ergonomics
Designed with a “Bantam” profile, this shotgun incorporates a reduced length of pull (typically 12.5-13 inches) and a scaled-down synthetic stock. This configuration optimizes handling and shouldering for shooters of smaller stature, or those who prefer a more compact platform. The synthetic construction ensures durability and weather resistance across varied operational environments.
Reliable Pump Action
Utilizing the venerable Mossberg 500 pump action, this shotgun incorporates twin action bars for smooth, non-binding operation. The ambidextrous tang safety provides intuitive and positive engagement, suitable for both right- and left-handed shooters. This action is renowned for its consistent cycling and robust construction, ensuring operational readiness under demanding conditions.
Combo Barrel Configuration
The “Combo” package includes multiple interchangeable barrels. Typically, this comprises a vented rib field barrel for general sporting applications (e.g., 22-24 inches) and a shorter, plain barrel optimized for defensive or slug-shooting roles (e.g., 18.5-20 inches). This immediate availability of application-specific barrels eliminates the need for additional component acquisition, providing immediate operational flexibility.
