Magpul Industries PMAG Gen M3 Window 5.56x45mm/223 Rem 30-Rd OD Green Polymer Magazine

The Magpul PMAG 30 AR/M4 Gen M3 Window is a 30-round polymer magazine chambered in 5.56x45mm NATO and compatible with .223 Remington, purpose-built for AR-15/M4-pattern firearms. This windowed variant of Magpul's flagship Gen M3 line features a OD Green polymer body with side windows that let the shooter visually confirm round count at a glance.

Built from next-generation polymer construction, the PMAG 30 Gen M3 Window delivers the durability and feeding reliability Magpul PMAGs are known for. The OD Green body stands up to cold, heat, and hard use typical of regular range and field work, and the windowed design makes round-count checks fast and intuitive.

Designed for AR-15, M4, M16, and similar 5.56mm/.223 Remington rifles and carbines, this PMAG ships ready for duty as a factory replacement or a high-capacity spare magazine.
