Product Description

The 4MM Full Metal Jacket (FMJ) arrows by Easton stand out for their unmatched penetration and precision. The micro-diameter design focuses on optimizing front-of-center for easier broadhead tuning and enhancing durability. The FMJ’s construction begins with an advanced carbon core for strength and light weight, encased in a full metal jacket to boost kinetic energy, accuracy, and ease of target removal. This powerful combination ensures deep penetration and increased pass-through impacts, leading to quicker kills and more substantial blood trails.

Pre-installed 4mm Microlite nocks and an aluminum point outsert (50 grains) are included for improved front-of-center balance and hunting effectiveness. The FMJ arrows are available in straightness tolerances of ±.002” and a Match Grade version at ±.001”, for top tier accuracy.
