Description
The PMAG 10/30 Gen M3 solves the puzzle for AR owners in restricted areas. You get all the handling and ergonomics of a full-size 30-round magazine, but internally limited to 10 rounds through a proprietary lock plate that's permanently secured with an aluminum rivet. It's the practical middle ground between capacity restrictions and practical usability.
Next-Gen Construction Built for Real Use
Magpul engineered this magazine from crush and impact-resistant polymer that doesn't sacrifice durability for compliance. The constant-curve internal geometry works with a long-life stainless-steel spring to feed smoothly and reliably, shot after shot. The bolt catch notch has been redesigned for increased clearance, and an over-insertion stop prevents the magazine from seating too far into your magwell. All the reliability features that made the GEN M3 line the standard for AR platforms came with this design.
Controls and Handling You Know
The standard 30-round profile means your mag pouches, your grip, and your shooting manual of arms stay exactly the same. Low-profile ribs and aggressive front-and-rear texturing give you solid control even with wet or gloved hands. A paint pen dot matrix on the bottom panel lets you mark and identify your mags at a glance. The clearly marked lock plate tab makes capacity obvious without any ambiguity.
Built in the USA
Made in the United States by Magpul Industries, this magazine brings the same manufacturing standards and quality control you'd expect from a company that's spent years earning its reputation in the AR market.

Frequently Asked Questions
Will the PMAG 10/30 fit in my standard magazine pouches?
Yes. The 10/30 retains the full 30-round form factor, so it works with any standard MOLLE or belt-mounted mag pouch designed for 30-round magazines. This is one of the main reasons people choose it over a true 10-round magazine.
Can the capacity lock be removed or modified?
No. The lock plate is permanently secured with an aluminum rivet, so it cannot be removed or altered. This magazine is not designed or intended to be modified in any way.
How does the PMAG 10/30 compare to actual 10-round magazines?
The 10/30 is taller and heavier because it maintains the full 30-round profile. You get all the advantages of that familiar size and ergonomics, along with the same proven reliability as other GEN M3 PMAGs. If you prefer a truly compact magazine for carry, a traditional 10-rounder might be your choice instead.
Does this magazine work in all AR-15 pattern rifles?
The PMAG Gen M3 line was engineered for broad compatibility, including standard AR-15s, M4s, and other Colt-spec platforms. Some users report seating issues when fully loaded to 10 rounds, though many others report no problems. If you encounter this, loading with 9 rounds typically resolves the issue.
