Mag Msbrg 590m 12ga 15rd Dbl Stk Blk

The Mossberg 590M 12 gauge 15-round double-stack magazine is a factory OEM polymer magazine engineered for reliable ammunition feeding in the Mossberg 590M mag-fed shotgun platform. Built to Mossberg's original specifications, this 15-round capacity magazine delivers consistent performance across repeated duty cycles and training applications where magazine-fed shotgun logistics demand dependable reload speeds and proven feeding reliability.

The double-stack configuration maximizes ammunition capacity while maintaining a compact footprint that facilitates faster magazine changes compared to tube-fed shotgun reloads. This magazine is chambered for 2¾-inch shell length only, a critical specification that ensures proper feeding geometry and prevents cartridge damage or feeding failures that can occur with longer magnum loads. The polymer body resists corrosion from exposure to solvents, moisture, and field conditions while remaining lightweight at 1.75 pounds loaded. Dimension-wise, the magazine profile measures 4.4 x 2.7 x 13 inches, fitting the dedicated mag well of the 590M platform without modification.

This magazine serves tactical training, law enforcement qualification, and serious sport shooting environments where the 590M's magazine-fed system offers faster reload sequences than traditional tube-fed shotgun designs. Operators running dedicated-feed shotgun setups benefit from Mossberg factory magazines that maintain the exact tolerances and feed lips required for zero-malfunction performance. For anyone operating a 590M, owning multiple high-capacity magazines ensures consistent drills and eliminates downtime between training blocks or duty shifts.
