Regardless of which arrow you shoot, you no longer need to choose between moon, capture, or flat nocks. TenPoint’s patented all-purpose Omni-Nock™ makes these special-purpose nocks obsolete. The Omni-Nock design features six micro-grooves that form three bowstring channels which eliminate the indexing problem associated with moon and capture nocks. - 12-pack of Omni-Nocks - Salmon - Pro-V22 Carbon Arrow
