TenPoint's Alpha-Nock features a deep bowstring groove, a large smooth radius base, and elongated ears. The string on TenPoint's extremely narrow crossbows wraps tightly around the center of the Alpha-Nock resulting in straight nock travel and precision down-range accuracy, while minimizing string serving wear.
The Alpha-Nock's deep groove and large radius base "holds" the bowstring in place on extremely narrow crossbows to prevent "shoot-over" or "shoot-under".
