Easton 4mm FMJ Arrow Shafts

The Easton 4mm FMJ carbon arrow shafts are engineered for bowhunters who demand maximum penetration, reduced wind drift, and dependable accuracy. Featuring an ultra-micro 4mm diameter, these Full Metal Jacket shafts minimize friction in flight and through the target to deliver industry-leading penetration and consistent downrange performance. Manufactured in the USA, Easton 4mm FMJ shafts combine a strong carbon core with a precision-drawn 7075-alloy aluminum jacket to increase kinetic energy, durability, and momentum. This configuration includes 50-grain aluminum 8-32 half-out inserts to strengthen the arrow front end and enhance front-of-center balance, along with pre-installed 4mm Microlite nocks for reliable release. Designed for serious bowhunters, Easton 4mm FMJ shafts deliver confidence-inspiring performance when penetration matters most.
