Mag Fn Five-seven Mrd 5.7x28mm 20rd

The Mag Fn Five-seven Mrd 5.7x28mm 20rd magazine is a factory-original polymer feed device engineered for the FN Five-seveN MRD platform. Designed for law enforcement, military, and civilian operators who rely on the Five-seveN's distinctive ballistic performance and ergonomics, this 20-round magazine delivers reliable ammunition storage and feeding in a lightweight, durable package. The 5.7x28mm cartridge occupies a specialized niche in tactical arsenals due to its reduced recoil, lower noise signature, and flat trajectory characteristics—making compatible magazines critical infrastructure for consistent fieldwork.

Constructed from reinforced polymer, the Mag Fn Five-seven Mrd 5.7x28mm 20rd magazine utilizes a proven single-stack geometry optimized for the Five-seveN MRD's magazine well dimensions. The polymer construction provides corrosion resistance and negligible weight penalty (0.25 lbs per magazine), critical for operators managing ammunition load in extended operations. Feed lips are precisely molded to maintain round alignment during chambering, minimizing failures to feed and ensuring consistent ignition cycles. The magazine's compact profile (2.5 x 1.25 x 6.5 inches) integrates seamlessly into the MRD platform without altering weapon handling or creating sharp edges that compromise tactical carry.

This magazine serves operators requiring authentic OEM-spec magazines for the FN Five-seveN MRD, whether for duty rotation, training cycles, or backup ammunition staging. Law enforcement units fielding the Five-seveN for specialized applications—including low-penetration environments or reduced-noise requirements—depend on factory magazines to maintain reliability standards and avoid drift between duty and training weapons systems. Compatible exclusively with the FN Five-seveN MRD platform, the 20-round capacity balances reload frequency with realistic patrol or tactical carry constraints. For units transitioning to the 5.7x28mm platform or expanding existing magazine pools, purchasing multiple Mag Fn Five-seven Mrd 5.7x28mm 20rd magazines ensures sufficient rotation for maintenance cycles and operational redundancy.
