Barnett Outdoors Demun Hyperbolt Features The Barnett Outdoors Demun Hyperbolt is built from carbon construction a material choice that keeps each bolt lightweight while still providing the stiffness needed for consistent flight and penetration. Carbon bolts resist bending and warping better than aluminum alternatives which helps shooters maintain tight repeatable groups across many shots. Matching bolts within the same set as this 6-pack does reduces the variation in weight and spine that can otherwise show up as flyers downrange. That consistency matters most at extended crossbow ranges where small differences compound into real point of impact shift. Sold as a set of six the Demun Hyperbolt gives a shooter enough bolts to sight in a crossbow and still head to the field with a full quiver. Having matched bolts on hand also means a lost or damaged bolt can be replaced without introducing a different spine or weight into the rotation. The 4 inch size referenced on this listing corresponds to the bolt s fletching or vane specification within the Hyperbolt line. For crossbow hunters and target shooters who want a dependable supply of carbon bolts from a trusted name in archery the Barnett Outdoors Demun Hyperbolt is available for sale at GrabAGun.
