TenPoint Crossbow Bolt 6-Pack

From the Amazon Listing

• CARBON CROSSBOW ARROWS - The 20-inch Pro Elite 400 carbon crossbow arrow is fletched slightly offset with 3.5″ Bohning X Vanes.
• ACCURACY - Pro Elite arrows are inspected for straightness to within .003, hand-sorted for weight tolerance to within 2-grains per dozen, and fitted with a 46-grain aluminum insert, generating a 13% FOC.
• ALPHA-NOCK HP - TenPoint’s Alpha-Nock features a deep groove & large smooth radius base to hold the bowstring in place & prevent “shoot-over” or “shoot-under”. Its HP Aluminum Bushing provides increased strength & accuracy.
• 28% INCREASED STRING-TO-NOCK ENGAGEMENT - The string on TenPoint’s extremely narrow crossbows wraps tightly around the center of the Alpha-Nock resulting in straight nock travel & precision down-range accuracy, while minimizing string serving wear.
