The Flatline 460 is a reverse-draw TenPoint that ships with the short 16-inch EVO-X CenterPunch16 carbon arrow, not a 20-inch bolt, and it carries the Alpha-Nock HP. As a current TenPoint it falls under the post-2019 Alpha-Nock requirement.
It takes the 16-inch CenterPunch16, not a 20-inch arrow, and only the Alpha-Nock HP. A flat or Omni nock voids the warranty and risks a dry-fire on a bow this fast.
