Magpul PMAG 40 GEN M3: Reliable 40-Round .223 Mag for Tactical Use

Reliable magazines are core components of any defensive AR platform. When mission readiness matters, feeding consistency, durable materials, and intuitive handling separate high-performing magazines from the rest.

MAGPUL PMAG is a 40-round 5.56×45 NATO / .223 Remington polymer magazine engineered for tactical use and extended-capacity applications. MAGPUL PMAG 40 GEN M3 product image

Design and feeding reliability

The MAGPUL PMAG features constant-curve internal geometry paired with a long-life stainless steel spring and a four-way anti-tilt follower to promote smooth, consistent feeding in AR15M4-compatible platforms. Toolless disassembly makes cleaning straightforward in the field or at the range, and the included pop-off impact/dust cover protects the top cartridge during storage and transit. For pricing, the PMAG is listed at about $21.80, offering strong value for its materials and functionality. Shop this product

Ergonomics and interface features

Low-profile ribs and a more aggressive front and rear texture deliver positive control in wet or gloved conditions. A bolt catch notch at the rear improves bolt catch clearance while an overtravel stop on the spine helps prevent over-insertion on compatible receivers. The flared floorplate aids extraction and handling and is slightly slimmer to fit tight double and triple pouches without sacrificing drop protection.

Compatibility and battlefield adaptability

Optimized for Colt-spec AR15M4 platforms, the MAGPUL PMAG also functions with a range of other weapons when modified — including HK-style systems, MR556/M27 variants, British SA80 platforms, FN SCAR configurations, and more. The constant-curve geometry and robust spring design help ensure reliable function across these systems.

For unit marking and inventory control the magazine includes a paint-pen dot matrix on the bottom panel so end users can add identifiers without compromising structural integrity. This small feature streamlines logistics for training, armories, and multi-weapon kits. View product details and pricing
