TenPoint Non-Lighted Pro Elite 400 Carbon Crossbow Bolt - 6 Pack - The Non-Lighted Pro Elite 400 20-inch carbon crossbow arrow is fletched slightly offset and is fitted with a 61-grain aluminum insert, 3.5in Bohning X Vanes and TenPoint’s white Alpha-Nock and receiver for quick lighted nock installation. Pro Elite shafts are inspected for straightness to within .003 and hand-sorted for weight tolerance to within 2-grains per dozen. The Alpha-Nock can be used in any TenPoint, Wicked Ridge, or Horton Crossbow Innovations crossbow. Use of the Alpha-Nock 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.
