Tenpoint CenterPunch HPX Alpha Blaze Features The TenPoint CenterPunch HPX Alpha Blaze arrow is engineered around a dual-layer carbon construction with a unidirectional carbon inner layer that adds stiffness and a woven carbon fiber outer layer that boosts impact strength against hard contact. This combination lets the 20 inch shaft hold up to repeated hits on 3D targets and game without sacrificing flight consistency. A tight .001 inch straightness tolerance keeps every arrow flying true out of the crossbow while weight matching to within 1 grain per arrow across the 445 grain shaft reduces group-to-group variance downrange. The 3 inch Bohning X Vanes stabilize the arrow quickly after launch for a flatter more predictable trajectory. Each CenterPunch HPX in this pack is equipped with TenPoint s Alpha-Blaze HPX Lighted Nock which activates automatically when the bowstring pushes it into the nock bushing upon firing. The bright red illumination improves visibility of the arrow in flight helping hunters and shooters confirm hits and track shot placement in low light. The lighted nock deactivates with a simple pull and lasts approximately 24 hours once triggered ready again at a moment s notice. Sold as a 3 pack the TenPoint CenterPunch HPX Alpha Blaze gives crossbow hunters a dependable visibility-enhanced arrow for serious hunting trips.
