The Mossberg 500 FLEX Super Bantam delivers full-size performance in a youth-friendly platform, featuring an adjustable length of pull system that grows with the shooter. This 20-gauge shotgun combines the reliability of the proven 500 action with ergonomic features specifically engineered for smaller-framed shooters.
What Makes This Different
The FLEX system sets this shotgun apart from fixed-stock youth models through its tool-free adjustability. The length of pull adjusts from 12" to 13" without requiring gunsmith modifications or additional purchases. The EZ-Reach forend reduces stretch distance by 1.5" compared to standard 500 models, while maintaining full functionality of the dual action bars.
Key Features
- FLEX TLS (Tool-Less Locking System) allows length of pull adjustment from 12" to 13"
- 20-gauge 3" chamber handles everything from target loads to waterfowl ammunition
- 22" vent rib barrel with Accu-Set choke system (Modified, Improved Cylinder, Full)
- EZ-Reach forend reduces reach by 1.5" for comfortable pump operation
- 5+1 capacity with dual extractors and positive steel-to-steel lockup
- Ambidextrous thumb safety and tang-mounted design

Field testing confirms this platform handles 2¾" and 3" shells with consistent cycling across load weights from 7/8 oz to 1¼ oz. The vent rib barrel reduces mirage during extended shooting sessions while providing a clear sight plane. Weather resistance comes from the blued metal finish and synthetic stock materials that resist moisture and temperature changes.
