The Centrum Premier combines industry-leading ±0.001-inch straightness, NO SPINE Technology, premium high modulus carbon construction, and the ARCOS system to deliver elite-level accuracy and consistency. What is NO SPINE Technology? NO SPINE Technology is Altra's proprietary manufacturing process that improves arrow tunability and consistency by reducing traditional spine-related variables. Are components included with the shafts? Yes. Each shaft includes the A.R.C.O.S. Insert/Outsert System and nocks. How accurate are these shafts? The shafts feature a verified straightness tolerance of ±0.001 inches and are weight matched to within ±1 grain per package. What type of target is recommended? Altra recommends using foam-style targets when shooting arrows equipped with the ARCOS system. Bag-style targets may cause the outserts to become lodged in filler material, potentially damaging the insert/outsert system or arrow. Available Spine Options Available in multiple spine sizes (see Altra Spine Chart for proper selection) The Pinnacle of Precision & Performance Built with advanced materials, industry-leading tolerances, and innovative NO SPINE Technology, the Altra Archery .166 Centrum Premier Arrows deliver the consistency, tunability, and confidence required by archers who expect the absolute best from every shot.
