A favorite choice for serious bowhunters looking for deep-penetrating big game performance. Axis carbon arrows deliver the extreme penetration of micro-diameter carbon, while Hidden Insert Technology aligns broadheads for tighter groups. Our straightness measurements are actual, and surpass, with a far more stringent straightness requirement, ATA/ASTM industry standard. We measure straightness based on the full length of the shaft, minus two inches, which makes Easton arrows the most accurate in the industry. What we say is what you get and better.
