FN Five-seveN MRD | 5.7×28 4.8″ FDE | MP# 66101277

The FN Five-seveN MRD is an optics-ready variant of FN’s compact 5.7x28mm pistol, fitted with a 4.8-inch cold hammer-forged barrel and a Flat Dark Earth polymer frame. The MRD system uses removable adapter plates to accept multiple common micro-optic footprints, so sights and dots can be mounted without custom fitting. The pistol ships with two magazines and adjustable iron sights that co-witness with many micro red dots. Recommended optic pairing under $1,000: a compact micro red dot such as the Holosun 507K or equivalent for low-profile mounting and quick target acquisition.
