The Carbon Express Maxima Red SD Stone Shafts are built for bowhunters who demand extreme accuracy, strength, and penetration in a small-diameter platform. Featuring Tri-Spine/RED ZONE Technology, these shafts dramatically reduce oscillation, delivering up to four times the accuracy of traditional single-spine arrows. With a .203″ inner diameter, they offer maximum kinetic energy and reduced crosswind drift. Constructed with BuffTuff Plus, BuffTuff, and Diamond Weave layers across the shaft for optimized strength, durability, and spine consistency, these arrows are engineered for consistent flight. Laser Match Set sorting and a real straightness of +/- .002″ ensure exceptional shot-to-shot reliability, while BullDog Nock Collars provide added rear-end protection.
