Go fast or go heavy! The Easton Sonic 6.0 is a 6mm high-performance hunting arrow engineered with high-performance speed and hunting accuracy in mind. The Sonic 6.0 is built from scratch in the USA using Easton’s seamless ACU-Carbon process for 100% weight and spine consistency from shaft to shaft and from dozen to dozen. Lighter overall mass weight also provides for a wider-range of arrow build options; from light-weight speed setups to high-FOC/high-momentum heavyweights.
