Warne Mag Extension for P-Mag 556 +5/rd

The Warne Mag Extension for P-Mag 556 with +5-round capacity is a direct-fit extension designed to increase magazine capacity on standard 30-round PMAG 5.56 NATO magazines. Manufactured by Warne Manufacturing Company, this extension allows operators to maximize round count without requiring a complete magazine change, making it an efficient solution for extended range sessions, tactical training, and high-volume shooting scenarios.

The extension features an ergonomic profile that facilitates smooth insertion and removal during mag changes under time pressure. Molded finger grooves provide positive grip and control when stripping the magazine from mag pouches or weapon platforms, reducing fumbling during transitions. At 0.22 lbs and compact dimensions, the extension adds minimal weight or bulk while delivering a straightforward 5-round capacity bump—useful for 5.56 NATO/.223 Remington shooting without over-extending magazine length. The design integrates seamlessly with existing PMAG 30 magazines, requiring no modifications to the parent magazine.

This extension suits military personnel, law enforcement, competitive shooters, and civilian enthusiasts who rely on PMAG platforms and want flexible capacity options. Whether running a rifle build on 5.56 for patrol, training, or competition, magazine extensions provide a practical middle ground between standard capacity and full-size alternatives. The Warne extension is compatible with standard PMAG 30 bodies and works across AR-pattern rifles and other 5.56-compatible platforms.

Warne Manufacturing has built a reputation for producing purpose-driven tactical accessories that undergo real-world testing. Magazine extensions occupy a niche category in the aftermarket ecosystem—not as essential as the magazine itself, but valuable for shooters seeking incremental capacity gains without investing in additional full-size magazines. The +5 configuration represents a practical balance between added firepower and minimal complexity or compatibility concerns across standard AR platforms.
