Magpul
The Magpul PMAG 30 Gen M3 Window is a 30-round 5.56x45 NATO polymer magazine purpose-built for AR15 and M4 platforms, but engineered with the versatility to run reliably in a broader family of modern rifle systems. If you're building or maintaining an AR, stocking up for the range, or outfitting a duty rifle, this magazine delivers the dependable feeding, durable construction, and smart features that have made PMAG the standard in the field.
The Gen M3 Window's dual translucent panels let you glance at your mag and know roughly how many rounds you have left—no fumbling, no guessing. Magpul's MagLevel system pairs those side windows with a high-visibility indicator coil on the spring and numerical markers on the body, so you get positive verification from 1 to 30 rounds. The polymer construction is impact and crush-resistant, designed to handle the realities of transport, storage, and hard use without degrading reliability. Inside, you get a proven architecture: constant-curve internal geometry, a self-lubricating anti-tilt follower, a long-life stainless steel spring, and an over-travel stop that prevents over-insertion on compatible platforms.
Handling is where the M3 shines. Aggressive front and rear texture, low-profile ribbing, and a redesigned slimmer floorplate give you positive control and easy disassembly without tools—important when you need to clean or inspect. The paint pen dot matrix on the bottom lets you mark your mags for quick identification. An increased bolt catch notch provides better clearance, and the floorplate is slim enough to stack in double and triple mag pouches without binding. This magazine is made in the USA and is compatible with AR15, M4, M16, and a wide range of modern STANAG 4179 platforms including HK416, SCAR MK16/16S, M27 IAR, and others.
Simple, proven, and purpose-built for shooters who demand reliability without compromise.

Absolutely. The PMAG 30 Gen M3 Window disassembles without tools, making it simple to clean the interior, inspect the spring and follower, and reassemble. The redesigned floorplate also aids in extraction and handling.
