FN 502™ MRD

Available for commercial, law enforcement, and military.

MSRP: $469.00

The 502 MRD is designed for maximum fun, but don’t let great range days mislead you, this red-dot-ready rimfire is built with enduring accuracy and quality in mind, patterned after its big brother, the FN 509. The target-grade fire control delivers faster, more accurate shots from an optics-ready platform. Mounting a favorite red dot and cycling a wide range of .22 LR ammo makes a low-cost range day a high-end experience. Superior ergonomics and ambidextrous controls make it perfect for high round count training sessions.
