The Magpul PMAG 30 AR/M4 GEN M3 Window is a detachable 30-round rifle magazine designed for firearms chambered in 5.56x45mm NATO or .223 Remington. This exact version is molded in Modified Coyote Brown and incorporates Magpul's dual-sided MagLevel window system, allowing the shooter to check the approximate remaining round count from either side of the magazine. A high-visibility indicator coil works with the markings beside each window to make the ammunition level easy to identify without removing the magazine from the firearm. The impact- and crush-resistant polymer body uses constant-curve internal geometry and a self-lubricating, four-way anti-tilt follower to support smooth cartridge presentation and dependable feeding. A long-life stainless steel spring provides consistent tension, while reinforced feed lips and an over-insertion stop help protect the magazine and support reliable operation during repeated loading and handling. Aggressive front and rear texturing, along with low-profile side ribs, offers a secure grip when drawing the magazine from a pouch or performing a reload. Paint-pen dot-matrix panels provide a convenient place to add identification markings without permanently altering the magazine body. The removable slimline floorplate aids handling and disassembly while maintaining compatibility with many double and triple magazine pouches. Although optimized for AR15, M4 and M16-pattern firearms, the GEN M3 geometry provides broad compatibility with many STANAG 4179-type platforms, including the HK416, MR556, M27 IAR, FN SCAR MK16/16S, IWI Tavor and SA-80. With a maximum length of 7.5 inches and an unloaded weight of 5 ounces, this American-made magazine delivers useful capacity, visible load status and practical handling features for range use, training or duty applications where legally permitted.Specifications and Features: 30-round capacity Modified Coyote Brown finish For 5.56x45mm NATO and .223 Remington Dual-sided MagLevel windows with round-count indicator Impact- and crush-resistant polymer body Self-lubricating four-way anti-tilt follower Long-life stainless steel spring Over-insertion stop and removable slimline floorplate Maximum Length: 7.5 in.
