Overview
The Mossberg 590M 12 Gauge 10 Round Magazine is engineered to optimize the operational capacity of your 590M series shotgun. This is a direct factory component, ensuring precise fitment and consistent performance under rigorous conditions. Designed for serious users, its construction prioritizes reliability and sustained engagement capability, making it suitable for competitive, tactical, or home defense applications requiring increased ammunition on demand.
Key Features
Enhanced Capacity and Operational Tempo
This magazine provides a substantial 10-round capacity for 12 Gauge ammunition. This increased payload significantly extends the user’s operational tempo between reloads, a critical advantage in high-stress scenarios where minimizing downtime is paramount. It allows for extended strings of fire, reducing the need for administrative manipulation.
Robust Construction for Durability
Manufactured to Mossberg’s specifications, the magazine features a precision-formed steel body, ensuring structural integrity and resistance to deformation. The robust construction is designed to withstand harsh field environments, impacts, and cyclic loading associated with high-volume use. A high-strength polymer anti-tilt follower works in conjunction with a heat-treated spring steel wire to ensure consistent upward pressure and reliable feeding throughout the magazine’s service life. The exterior is finished with a durable, corrosion-resistant coating to mitigate environmental wear.
Optimized Feeding Reliability
The internal geometry of the magazine, combined with the anti-tilt follower design, is specifically calibrated for the 12 Gauge cartridge within the 590M system. This precision engineering minimizes friction and prevents nose-diving or binding, ensuring smooth, uninterrupted cartridge presentation to the chamber. Consistent spring tension is maintained across all 10 rounds, supporting the reliable cycling of various 12 Gauge loads.
Seamless Integration and Security
As a factory component, this magazine guarantees a secure and positive lock-up within the Mossberg 590M’s magazine well. The precisely machined feed lips and retention points integrate flawlessly with the firearm’s receiver, facilitating quick, confident reloads while maintaining stability during firing sequences.
