specs differ
Flat nock and Ravin R500 clip-on nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Flat nock | Ravin R500 clip-on nock |
|---|---|---|
| Nock | flat (flat-back) nock | Ravin R500-series polymer nock |
| Form | plain flat disc on the shaft base, non-indexed | R500-specific polymer clip-on nock and bushing |
| Fits | Excalibur Micro series and older recurve crossbows | Ravin R500 Series only |
| Compatibility rule | The flight groove and rail must align the string to the centre of the flat base. Excalibur supplies flat-nocked arrows for the Micro series; it does not require proprietary arrows but cautions against anything under 350 total grains. | 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. |
