Easton Archery???s 5mm FMJ Autumn Orange Arrows combine tradition with the latest manufacturing innovations. Finished with the classic Easton Autumn Orange anodize, these arrows lower friction and drive deeper through bone and hide. Like all of the arrows in Easton???s FMJ series, the 5mm FMJ features a technologically advanced arrow shaft designed for penetration, accuracy, and clean kills. The FMJ starts as a carbon foundation using the Accucarbon process of fusing high-strength carbon fiber with aerospace grade resin for a more consistent spine and weight. This carbon fiber core is then permanently bonded inside of an aluminum tube, and the synergy between the two creates greater ballistics efficiency, more impact energy, and more momentum. The result is an arrow that???s highly effective on larger game.
