Hunting accuracy for shooter confidence is the cornerstone of Easton 6.5 arrows. The 6.5 uses proprietary Acu-Carbon™Uniform Spine process. Acu-Carbon™ is a continuous-fed, single-die manufacturing method that results in the most reliable tolerances and eliminates the need for the spine-alignment and weight sorting. Easton’s Acu-Carbon™ production line produces the most consistent spine and weight from dozen to dozen and lot to lot—year in and year out. This benefits the bowhunter with truer flight and pinpoint accuracy in the field. The Easton 6.5MM™ arrows are USA-made shafts that offer the highest level of accuracy available to bowhunters today all at price points to fit virtually any budget. The Easton 6.5 includes NEW 6.5MM inserts that are made using a 4X-larger shoulder to add strength and boost valuable FOC.
