Easton 4mm FMJ Arrow Shafts – 6 Pack

Easton 4mm FMJ shafts are built for bowhunters who want maximum penetration and minimal wind drift from a tough, consistent hunting arrow. The ultra-micro 4mm diameter cuts through the wind and reduces friction on impact, driving deeper through tissue and bone for more effective blood trails and quicker recoveries. At the core is a lightweight, high-strength carbon shaft wrapped in a precision-drawn 7075 aluminum jacket, delivering a blend of straightness, kinetic energy, and durability that has made FMJ one of the most trusted hunting shafts on the market.​

Each shaft comes with pre-installed 4mm Microlite nocks and Easton’s 4mm 8-32 aluminum Half-Out (approx. 50 grains) to optimize FOC for hunting setups while maintaining broadhead compatibility. The slim 4mm profile also makes target removal easier compared to standard all-carbon shafts, while the metal jacket helps resist shaft damage in dense targets and real-world hunting impacts. Offered in four popular spine options from 400 to 250 and made in Easton’s USA facility, the 4mm Full Metal Jacket is designed to cover virtually all modern compound hunting bow setups with tight tolerances and dependable accuracy.
