WHAT IS A “FULL METAL JACKET®” ARROW? Full Metal Jacket (FMJ) technology is a patented arrow construction only from Easton. This revolutionary arrow combines the best attributes of carbon and aluminum in a heavy-duty configuration. The small diameter and thick wall carbon-fiber core with Hidden Insert Technology (HIT) provides superior penetration, durability and accuracy. The aerospace alloy aluminum jacket provides more consistent spine, straightness, and higher stored energy than all-carbon arrows. The end result is an arrow with outstanding accuracy, durability and bone-crushing penetration. In addition, when compared to all-carbon arrows, FMJ’s innovative metal jacket design delivers easy arrow removal from tough, high-density 3D targets. 📷: @savageoutdoors_theone #eastonarchery #eastonarrows #eastonfmj #arrows #archery #easton #bowhunting #madeinusa #usamade
