The Mossberg 590M 12-gauge 5-round double-stack magazine in black is a factory-original magazine engineered for the Mossberg 590M mag-fed platform. Built to the same specifications and tolerances as OEM Mossberg equipment, this polymer-bodied magazine delivers reliable ammunition feeding and superior fit with zero compatibility guesswork.
The double-stack configuration maximizes round capacity in a compact footprint while the polymer body resists corrosion in harsh environments—a critical advantage over steel alternatives in coastal, humid, or extended-deployment scenarios. The magazine is purpose-designed for 2-3/4-inch shotshell length only, ensuring proper feeding cycles and preventing the reliability issues that arise from mixed ammunition lengths. At 1.19 pounds per magazine, weight is negligible during extended shooting sessions or tactical deployments, while the black polymer finish blends seamlessly with modern shotgun aesthetics and reduces visual signature.
This magazine is built for operators, law enforcement, and serious shooters running mag-fed 590M systems in training, patrol, or home-defense roles. Mossberg factory magazines eliminate the guesswork of third-party components and ensure the feeding reliability that defines a mission-critical firearm. Replacing worn magazines or adding spares to your loadout maintains peak operational readiness without functional compromise.
The 590M platform represents a shift toward modern, combat-inspired shotgun design, and OEM magazines are the foundation of that reliability. Polymer construction, proven feeding geometry, and Mossberg's manufacturing standards make this a straightforward upgrade or replacement for any 590M mag-fed operator.
