TENPOINT ALPHA NOCK MOLDED RED For use with all TenPoint and Wicked Ridge crossbows. All TenPoint and Wicked Ridge crossbows require the use of an Alpha-Nock arrow. Failure to do so will void the manufacturer’s warranty. Increases String-to-Nock Engagement by 28% TenPoint’s Alpha-Nock features a deep bowstring groove, a large smooth radius base, and elongated ears. The string on TenPoint’s 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”. *Available as a 6-pack
