Salt Lake City, Utah – Easton introduces a new addition to the FMJ flagship line—the 4MM FMJ. The 2021 4MM Full Metal Jacket has been updated with a new spine configuration, an all-new 8-32 point half-out system, and redesigned graphics.

Full Metal jacket arrows are the archery industry’s flagship hunting arrow because they offer the highest level of penetration and accuracy.  Dual material carbon/aluminum construction guarantees precision and adds the critical punch of more kinetic energy. FMJ arrows pull more potential energy from the bow and increase penetration by focusing their mass into a smaller diameter and reduced surface area. This results in less friction during flight for higher speed and more kinetic energy downrange. The ultra-micro diameter also penetrates with less friction within the target for more pass-through impacts to take down game quickly and hasten recovery.  The slick aluminum surface further reduces friction for even more penetration, and it offers noticeably easier extraction when pulling shafts from practice targets.

FMJ 4MM comes pre-installed with 4MM nocks and includes Easton’s new aluminum point half-out. The half-out optimizes front-of-center for easier broadhead tuning and more durability and is compatible with standard thread 8-32 broadheads and field points. Available in the most popular hunting spine sizes: 250, 300, 340, and 400.  Offered in both standard and Match Grade models.
