specs differ
Half-moon nock and Ravin R500 clip-on nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Half-moon nock | Ravin R500 clip-on nock |
|---|---|---|
| Nock | half-moon (moon) nock | Ravin R500-series polymer nock |
| Form | shallow concave groove across a flat disc; must be indexed to the string | R500-specific polymer clip-on nock and bushing |
| Fits | CenterPoint, most Barnett non-Hyper models, and many entry and mid crossbows | Ravin R500 Series only |
| 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 R500 uses an R500-specific arrow and nock. The standard Ravin.003 arrow is explicitly not compatible with the R500 Series, and the R500 arrow is for the R500 only. |
