The FN 502 MRD is a hammer-fired .22 LR pistol built around the ergonomics of the FN 509 family. Its balanced slide and frame, crisp trigger, textured polymer grip, and fully ambidextrous controls provide comfortable handling for training and range use. The FN Low-Profile Optics-Mounting System accepts multiple micro red dot footprints through interchangeable mounting plates, while suppressor-height sights provide a clear sight picture. The four-inch threaded barrel adds compatibility with suitable muzzle accessories, and the pistol includes two 10-round flush-fit magazines.
