specs differ
Half-moon nock and TenPoint Omni-Nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Half-moon nock | TenPoint Omni-Nock |
|---|---|---|
| Nock | half-moon (moon) nock | Omni-Nock (legacy TenPoint) |
| Form | shallow concave groove across a flat disc; must be indexed to the string | six-groove nock so the string finds a channel at any rotation, non-indexed |
| Fits | CenterPoint, most Barnett non-Hyper models, and many entry and mid crossbows | Pre-2019 TenPoint and Wicked Ridge crossbows, replaced by the Alpha-Nock |
| Compatibility rule | The groove must be indexed square to the string on every shot. If the odd-coloured (index) vane is not down, the string can sit on the rim of the nock and dry-fire the bow. | The Omni-Nock was TenPoint's standard before the Alpha-Nock. TenPoint now specifies the Alpha-Nock on all 2019-and-newer bows, so an Omni-Nock should only be shot on the older bows it shipped with. |
