The Easton 5mm FMJ carbon arrow shafts are built for bowhunters who demand penetration, durability, and strength when pursuing tough game. Featuring a high-strength carbon core wrapped in a 7075-alloy metal jacket, FMJ shafts deliver added kinetic punch while maintaining a small-diameter profile that reduces friction and increases penetration. Made in the USA, Easton 5mm FMJ shafts in this configuration include precision-machined 25-grain aluminum 8-32 half-out inserts to reinforce the arrow front end, improve broadhead alignment, and enhance front-of-center balance. Pre-installed 5mm X Nocks ensure reliable string fit and consistent release.
