The FN 15 Guardian is a dependable 5.56 NATO semi-automatic rifle built around a proven AR-pattern design. Its 16-inch nitrided chrome moly vanadium steel barrel delivers consistent accuracy, while the mid-length direct-impingement gas system helps reduce recoil and improve handling. A 15-inch free-float aluminum M-LOK handguard provides a stable mounting platform for accessories and user-installed aiming equipment. The six-position adjustable stock, stippled pistol grip, and textured magazines support a secure, comfortable shooting position for home defense, training, and recreational use.
