Windowed PMAG® 30 AR/M4 — 30 rounds — 5.56×45 mm NATO — Magpul®

PMAG^® 30 — a rugged, windowed 30-round magazine for 5.56×45 mm NATO platforms. Reinforced next-generation polymer construction, stainless-steel spring and a clear witness window for quick round-count checks.

Next-generation polymer, engineered for durability

Manufactured from a reinforced, impact-resistant polymer compound, this PMAG is designed to resist wear, shocks and environmental stress while remaining lightweight. The material and construction contribute to extended service life and reliable field performance.

Positive handling and secure retention

The magazine features a patterned texture that delivers a secure grip for fast, confident magazine changes. An internal anti-overtravel stop limits excessive follower movement for consistent feeding, and the extended base design improves extraction from pouches and adds drop protection.

Witness window and easy maintenance

A transparent witness window provides a quick visual indication of remaining rounds without removing the magazine. Tool-free disassembly permits fast field maintenance and cleaning to keep internals operating smoothly.

Reliable internals

A durable stainless-steel spring is specified for long life and consistent spring force. The magazine’s internal geometry and follower are engineered to promote reliable feeding across a wide range of AR-pattern rifles.
