Description
The PMAG 10 Gen M3 is built for situations where you need a lower profile without compromising on dependability. Designed in Olive Drab Green, this magazine packs the same proven features that Magpul integrated into their full-size Gen M3 line, just in a compact 10-round package that fits nearly flush in your magwell.
Given that this is Gen M3 technology, you're getting next-generation materials and manufacturing processes. The impact and crush-resistant polymer body stands up to the kind of abuse that happens in real-world use, while the reinforced feed lips keep things running smooth. The long-life stainless steel spring paired with the four-way anti-tilt follower means your rounds feed reliably regardless of environmental conditions or how your rifle is angled.
Gen M3 Design Elements in the 10-Round Format
The compact profile makes this magazine ideal for prone shooting and bench rest work where a 30-round mag creates clearance issues. But the reduced size doesn't mean reduced capability. Magpul engineered the constant-curve internal geometry to maintain the same feeding performance as their larger magazines, and the aggressive texturing on the front and rear gives you positive control even when things get wet or muddy.
Handling and Compatibility Features
The flared floorplate aids quick disassembly and removal, and it's slim enough to work with double and triple mag pouches. An over-travel insertion stop on the spine prevents over-insertion, while the redesigned bolt catch notch provides increased clearance. While optimized for Colt-spec AR15/M4 platforms, the modified geometry also works with non-standard platforms including the HK 416, FN SCAR, and others. Made in the USA.

Frequently Asked Questions
Will the PMAG 10 Gen M3 fit in my AR-15 magazine pouches?
Yes. The flared floorplate is slim enough to work with standard double and triple mag pouches. The compact length means it packs into pouches easily, though it will sit higher in the magazine well since it holds fewer rounds.
Is the Gen M3 10-round magazine compatible with my HK 416 or other non-Colt AR variants?
The PMAG 10 Gen M3 features modified internal and external geometry that makes it compatible with a wider range of platforms beyond standard AR-15s. This includes the HK 416/MR556A1/M27 IAR, FN SCAR MK 16/16S, British SA-80, and others. It's still optimized for Colt-spec platforms first, but the cross-platform capability is one of the Gen M3 improvements.
What's the difference between the PMAG 10 Gen M3 and older PMAG generations?
Gen M3 magazines feature next-generation impact and crush-resistant polymer, improved material technology, a redesigned four-way anti-tilt follower, and reinforced feed lips. The texturing is more aggressive for better grip control, and the floorplate is slimmer. All of these improvements make the Gen M3 more durable and reliable in real-world conditions.
Can I use the PMAG 10 Gen M3 for hunting or precision shooting?
Absolutely. The compact 10-round profile reduces the magazine's protrusion below the rifle, making prone shooting more comfortable and improving handling in tight spaces. It works great for hunting applications and bench rest shooting where a lower profile is beneficial.
