The CenterPunch 20-inch arrow is fletched slightly offset and is fitted with a 68-grain insert and TenPoint’s Alpha Nock HP and Alpha Nock HP Nock Bushing.Constructed from modulus carbon fiber at 33 MSI (million-pounds-per-square-inch) and wrapped in an exclusive LAZER-TECH carbon weave, it is fletched with 2.1″ Q2i Fusion-II Vanes. CenterPunch arrows are inspected for straightness to within .001 and each package is weight-grain matched within 1-grain per arrow.
TenPoint’s Alpha-Nock HP features a deep bowstring groove, a large smooth radius base, and elongated ears. Its HP Aluminum Bushing increases strength and accuracy. The string on TenPoint’s extremely narrow crossbows wraps tightly around the center of the Alpha-Nock HP resulting in straight nock travel and precision down-range accuracy, while minimizing string serving wear.
The Alpha-Nock HP’s deep channel design increases the string-to-nock engagement by 28% and “holds” the bowstring in place during the shot which prevents “shoot-over” or “shoot-under”.
The Alpha-Nock HP can be used in any TenPoint, Wicked Ridge, or Horton Crossbow Innovations crossbow. Use of the Alpha-Nock HP in any of these crossbows will not void the warranty, even if your crossbow originally required the use of a flat nock or Omni-Nock.
