The FN 502 MRD is a single-action-only .22 LR pistol designed for realistic, low-cost training and extended range sessions. Its controls and ergonomics are patterned after the FN 509, while the target-grade fire control supports a crisp, consistent shooting experience. The optics-ready slide accepts a wide range of micro red-dot sights, and the suppressor-height sights provide a useful aiming reference. A 4-inch threaded barrel adds compatibility with muzzle accessories, while the textured polymer grip and ambidextrous controls support confident handling for a broad range of shooters.
