The Easton 5.0 is the all-new lightweight, small diameter hunting arrow, designed for bowhunters seeking a versatile shaft that offers multiple setup options. Built on a micro-diameter 5mm Acu-Carbon platform, the Easton 5.0 reduces friction for enhanced penetration and decreases wind resistance for greater accuracy and higher velocity downrange. The lighter overall mass weight of the Easton 5.0 also allows for a versatile range of arrow setup options, from lightweight speed builds to high-FOC configurations. Crafted in the USA using Easton s seamless Acu-Carbon process and high-modulus carbon fiber, the 5.0 ensures consistent weight and spine in every shaft and across every dozen. Available in six spine sizes (200, 250, 300, 340, 400, and 500), the Easton 5.0 accommodates virtually all bowhunting setups. The 5.0 features Easton s new 5MM Microlite Nock System, which includes a more compact nock body and a redesigned throat for better string fit and enhanced tunability.
