FN Five-seveN MK3 20-Rd 5.7x28mm Black Polymer Pistol Magazine

The FN Five-seveN MK3 factory magazine is a genuine OEM 20-round replacement or spare magazine built specifically for the FN Five-seveN MK3 MRD pistol chambered in 5.7x28mm. It is NOT compatible with earlier Five-seveN Mk2 models, making it the correct magazine for current-production MK3 / MRD pistols.

The body, base plate, and feed lips are molded from durable, impact-resistant black polymer, keeping the magazine lightweight yet rugged enough for daily range and duty use. With a 20-round capacity, this magazine matches the count of the factory magazines that ship with the MK3 MRD, allowing shooters to maintain full capacity for range sessions, training, or topped-off carry rotations. The polymer construction also resists corrosion and stands up well to the high-velocity output of the 5.7x28mm cartridge.

This is a direct factory replacement for the magazine that originally ships in the Five-seveN MK3, so fit, function, and feed reliability are exactly what FN engineered for the platform. Whether you need a spare for the range, a replacement for a lost or damaged magazine, or an extra to keep your pistol fully loaded, this OEM unit is the right choice.
