The Black Eagle Spartan Shafts offer a unique combination of speed, accuracy, and devastating impact in a compact design. With a 5.7mm (.224″) inner diameter, the Spartan is the smallest arrow in its class that can still accept an insert, reducing drag while maintaining strength and penetration. Each shaft is super-sorted and spine indexed for maximum consistency in spine, straightness, and weight, with .001″ straightness and a +/- 1 grain weight tolerance. Built from premium carbon, the Spartan delivers exceptional durability and precision flight. Designed for the modern hunter, it sets a new standard for micro-diameter hunting arrow performance.
