Mossberg 500 20 Gauge Pump Shotgun 3" 24" Vent Rib Accu-Set

The Mossberg 56435 500 delivers reliable pump-action performance in a versatile 20-gauge platform that handles both 2.75" and 3" shells. This configuration combines a 24-inch ventilated rib barrel with Accu-Set choke system for adaptable shooting applications.

What Makes This Different

The Accu-Set choke system provides three interchangeable tubes (Full, Modified, Improved Cylinder) that transform this shotgun from waterfowl gun to upland bird hunter to turkey setup. The 24-inch barrel length strikes an optimal balance between maneuverability and velocity retention that 26-28 inch barrels offer. Mossberg's dual extractors and positive steel-to-steel lockup ensure consistent shell extraction under rapid cycling conditions.

Key Features

• Accu-Set choke system with three precision-machined tubes for versatile shot patterns
• 24-inch ventilated rib barrel reduces mirage and aids target acquisition
• Synthetic stock and forend resist weather damage and dimensional changes
• Ambidextrous thumb safety located behind trigger guard for intuitive operation
• Dual extractors prevent stuck shells during rapid follow-up shots
• Anti-jam elevator design minimizes feeding malfunctions
• Drilled and tapped receiver accepts scope mounts and accessories

Field testing demonstrates consistent 1200+ fps velocities with 3-inch loads while maintaining manageable recoil characteristics. The 20-gauge platform reduces felt recoil by approximately 25% compared to 12-gauge equivalents while delivering effective patterns out to 40+ yards with appropriate chokes. Weather sealing around the action prevents moisture infiltration during waterfowl seasons.
