TenPoint EVO-X CenterPunch Features The TenPoint EVO-X CenterPunch is constructed from modulus carbon fiber rated at 33 MSI and wrapped in TenPoint s exclusive LAZER-TECH carbon weave giving the shaft exceptional stiffness and straightness for consistent downrange performance. Every arrow in the 3-pack is inspected to within .001 inch of straightness and weight-matched within 1 grain so hunters can trust that each bolt flies the same as the last. The 87 grain brass insert with an inside diameter of .297 and outside diameter of .344 provides a secure properly weighted platform for broadheads or field points. Fletched with 3 inch Bohning X vanes for 17 percent F.O.C. the arrow is tuned for the accuracy TenPoint markets as the most precise crossbow bolt it has ever built. The Alpha-Blaze Lighted Nock is the standout feature of this arrow built as a one-piece nock and LED unit that indexes with the vanes and press fits into the arrow s aluminum bushing. Upon firing the bowstring s force compresses the nock and activates the light automatically with no manual switch required and the LED runs for approximately eight hours once lit. The nock deactivates just as easily pulling straight out until the light shuts off with no tools needed for either step. Because the Alpha-Nock HP bushing is compatible with any TenPoint Wicked Ridge or Horton crossbow without voiding the warranty hunters get both the accuracy of the CenterPunch shaft and the shot confirmation of a lighted nock in one complete 16 inch 3-pack arrow system.
