Easton 5mm Axis with Half-Out 400 Spine Carbon Arrows - 6 Pack - The hands-down proven small diameter all carbon arrows. Faster, Deeper, Deadlier. Millions of successful hunts testify to the awesome effectiveness of a simple concept that equates to more downed big game. The AXIS micro profile focuses the kinetic energy into an ultra-small frontal area for less friction and thus greater penetration. AXIS penetrates deeper as the shaft passes through animals with less friction behind the broadhead channel. The small diameter also means that AXIS arrows fly much better in crosswinds than regular carbon arrows. That means broadheads will find the aim-point more often in the field. Easton is proud to announce that 5mm AXIS arrows now come with factory helical fletching. With the new factory helical fletching, AXIS 5mm now offers more broadhead accuracy right out of the box. Factory helical fletching sets the vanes at a slight angle to the shaft, creating a helix shape that offers benefits of increased stability, improved arrow flight, and greater effective range, resulting in improved broadhead accuracy & easier tuning.
