The Black Eagle X Impact Shafts are precision-engineered for archers who demand maximum speed, accuracy, and performance. Featuring an ultra-slim 4mm (.165") diameter, these arrows minimize drag for blistering velocity and flat trajectory. Built with high-quality carbon and super-sorted for consistent spine, straightness, and weight, the X Impact delivers repeatable performance with every shot. The shafts include spine indexing, a straightness tolerance of .001", and a +/- 1 grain weight tolerance, with each 32-inch shaft optimized for penetration and stability. Included components like the FOCOS 2.0 system (excluding 600 spine), flo-orange M nocks, and nock collars allow for enhanced FOC tuning and improved accuracy.
