Built for speed, the Tenpoint Pro Elite 400 20" Carbon Crossbow Bolts are fletched slightly offset with 3.5" Bohning X Vanes and TenPoint's Alpha Blaze Lighted Nocks. The Pro Elite 400 is fitted with a 58-grain aluminum insert and inspected for straightness to within .003". 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.
