Anti-glare Translucent MagLevel Windows

The transparent window on the side of the magazine provides a quick and clear view of the remaining ammunition, allowing for better situational awareness during shooting sessions. The magazine also features a removable dust cover to protect the feed lips and ammunition from dirt, debris, and damage during storage or transport.

The Magpul M3 20 Rd Magazine also has a flared floorplate yet is slim enough for use with tight double and triple magazine pouches. The high-quality stainless steel spring inside is corrosion-resistant, and the integrated follower is self-lubricating with an anti-tilt feature for increased reliability.
