Easton loves a challenge. And there's no bigger challenge than improving on their hugely popular Full Metal Jacket arrow shaft. But they've done it by packing all the power of the original into a new 4MM micro diameter (.166" inside diameter) shaft. The FMJ 4MM will give you unmatched knockdown power!
The Precision 7075 alloy jacket is bonded to a carbon core to provide minimal friction and extraordinary strength. Pair that with the included outserts for increased FOC. You'll get deeper penetration and increased likelihood of pass-throughs on even the toughest of big game.
