EASTON 6.5MM MATRIX SHAFTS 250 1 DOZ. Easton unveiled a new light weight arrow in its 6.5mm product line—the 6.5 MATRIX. This new arrow is an ultra-light weight model that uses Easton’s Acu-carbon™ seamless process. The Matrix features a new carbon fiber braid visible on the outside of the shaft. The Easton’s proprietary process results in a seamless shaft delivering a virtually perfect spine and weight across every production run. Acu-carbon constructed arrows tune easier and offer better accuracy on the range and in the field.
