The Easton 4mm FMJ is the original Full Metal Jacket — the arrow that proved a carbon core wrapped in a precision-drawn 7075 alloy jacket could outpenetrate, outspeed, and outlast standard carbon shafts. Factory fletched with Blazer vanes and ready to shoot straight out of the box, this 6-pack is built for bowhunters who want the proven FMJ performance without the extra build time.
The ultra micro-diameter 4mm (.166" ID) profile minimizes friction at impact for deeper penetration on elk, mule deer, and bear, while the alloy jacket adds mass and kinetic energy without ballooning the diameter. Less wind drift, easier target pull, and more energy delivered downrange — all in a factory-fletched package ready for Colorado’s backcountry. Made in the USA.
