AR15/M4 PMAG magazine / 30 rounds, caliber 5.56x45 NATO Magpul®

PMAG^® 20 AR/M4 GEN M3 — a compact, highly reliable 20-round magazine for 5.56×45 mm NATO platforms. Built for durability, quick handling and low-profile carriage.

Compact design, uncompromised reliability

The PMAG^® 20 GEN M3 offers a compact footprint that benefits manoeuvrability, weight and concealability without sacrificing the durability or feeding reliability you expect from Magpul. Its reduced profile makes it an excellent choice for shooters who prioritise mobility, rapid handling and streamlined kit.

Designed for positive handling

Thoughtful ergonomics — including a patterned texture for secure gripping and a tactile dot-base for quick orientation — speed magazine changes under stress. The magazine’s size helps reduce snagging and improves insertion in tight positions while still providing a practical 20-round capacity.

Durable, field-ready construction

Constructed from impact-resistant polymer, the PMAG® 20 GEN M3 is built for long service life and hard use. The design focuses on consistent feeding and easy maintenance; disassembly for cleaning is straightforward to support rapid field servicing.

Use cases & compliance

This magazine is ideal for operators, competitors and trainers who value a compact, low-profile load option. The 20-round capacity also suits regions or events with magazine-capacity limits. Verify cartridge compatibility for your application — 5.56×45 mm NATO is the specified calibre; compatibility with .223 Remington is common but should be confirmed for your rifle.
