Magazine Magpul PMAG Gen M3 Window caliber .223 Rem (5.56×45) for AR/M4, 30-round (with window) is a full-capacity next-generation magazine that combines the proven reliability of the PMAG Gen M3 series with enhanced real-time ammunition monitoring. The design is engineered for consistent performance across a wide range of AR-pattern rifles in demanding operational environments.
The body is constructed from impact-resistant polymer, capable of withstanding drops, mechanical stress, temperature changes, and exposure to dust and debris. An integrated transparent window with a visual indicator allows continuous monitoring of remaining rounds without removing the magazine from the weapon. The internal geometry is optimized for smooth and consistent feeding of 5.56×45 mm cartridges, while the anti-tilt follower prevents binding or misalignment. A stainless steel spring ensures long-term durability and stable cycling. A removable dust cover protects feed lips and internal components during storage and transport.
