specs differ
Flat nock and Ravin clip-on nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Flat nock | Ravin clip-on nock |
|---|---|---|
| Nock | flat (flat-back) nock | Ravin polymer clip-on nock |
| Form | plain flat disc on the shaft base, non-indexed | polymer clip that snaps onto the string, over an aluminium nock bushing |
| Fits | Excalibur Micro series and older recurve crossbows | All Ravin crossbows except the R500 Series (R10, R18, R26, R29 and variants) |
| 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. | 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. |
