Design and ergonomics

Built by Fn and patterned after the FN 509, the FN 502 MRD [FDE] transfers centerfire ergonomics to a rimfire platform. The target-grade fire control is tuned for consistent trigger breaks, and the ergonomics — including textured grip and sight geometry — support fast, accurate follow-up shots during long range sessions. Ambidextrous controls make it suitable for left- or right-handed operators and reduce transition time when running drills.

Optics-ready platform and magazines

This model is red-dot-ready, letting you mount a favorite miniature reflex sight quickly for modern sighting solutions. The package includes two 10-round magazines, so you can keep drills moving without constant reloads. Cycling a wide range of .22 LR ammo, the FN 502 MRD [FDE] delivers reliable function across common rimfire loads — ideal for shooters who value variety in testing ammo and zeroing optics.
