Description
Magpul 5.56 magazine for sale — the PMAG 30 AR/M4 GEN M3 Window is a durable 30-round polymer magazine for compatible AR-15 and M4 platforms chambered in 5.56×45mm NATO or .223 Remington. It combines reliable PMAG construction with dual-side translucent MagLevel windows, allowing you to quickly estimate the number of rounds remaining.
The Magpul 30 round AR-15 magazine features an impact- and crush-resistant polymer body, a long-life USGI-spec stainless-steel spring, and a four-way anti-tilt follower for smooth, consistent feeding. Its constant-curve internal geometry helps maintain reliable cartridge presentation during range sessions, training, and other lawful shooting applications.
The built-in MagLevel system uses numerical markings and a high-visibility indicator coil to make ammunition checks easier without removing the windowed PMAG 5.56 magazine from the firearm. The transparent windows are designed to provide visibility while preserving the magazine’s durability and dependable operation.
For improved compatibility and handling, the GEN M3 Window includes a redesigned bolt-catch notch, an over-travel stop to help prevent over-insertion, and aggressive front and rear texturing for a secure grip. The slimmer flared floorplate supports positive extraction, improves drop protection, and fits more easily in tight double- and triple-magazine pouches.
The magazine can be disassembled without specialized tools, making cleaning straightforward. A paint-pen dot matrix allows easy identification, while the included Impact/Dust Cover helps protect the top cartridge during storage and transport.
