specs differ
Half-moon nock and Ravin clip-on nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Half-moon nock | Ravin clip-on nock |
|---|---|---|
| Nock | half-moon (moon) nock | Ravin polymer clip-on nock |
| Form | shallow concave groove across a flat disc; must be indexed to the string | polymer clip that snaps onto the string, over an aluminium nock bushing |
| Fits | CenterPoint, most Barnett non-Hyper models, and many entry and mid crossbows | All Ravin crossbows except the R500 Series (R10, R18, R26, R29 and variants) |
| 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. | Ravin warrants only its own clip-on nock; any other nock design negates the 5-year warranty. The clip physically captures the string so it cannot slip off the bolt at 400-plus fps. |
