The Mossberg 590M magazine is the world’s first production double-stack 12GA shotgun magazine, offering shorter magazine length versus capacity than competitor’s single-stack designs for better swing, balance and control. This 5-round magazine is engineered for the Mossberg 590M Mag Fed shotgun platform and is for use with 2.75″ shotshells only.
Magazine construction features hardened steel feed lips, over-molded steel shell ramps, easy-grip external molded design, proprietary self-lubricating polymer magazine body material, heavy-duty ASTM-A-228 music wire magazine spring, removable floor plate for easy cleaning, and a tough black oxide finish on steel components. This compact magazine is engineered for reliable, repeatable feeding with a combination of polymer construction and hardened steel contact points that prioritize wear resistance and ease of maintenance for range, duty, or field applications where consistent function matters.
590M magazines are available in 5, 10, 15, and 20-round capacities for shooting flexibility. The removable floor plate makes field maintenance simple, while the durable construction ensures dependable performance in demanding conditions.
