specs differ
Excalibur Rhino nock and Ravin clip-on nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Excalibur Rhino nock | Ravin clip-on nock |
|---|---|---|
| Nock | Rhino nock (Excalibur half-moon) | Ravin polymer clip-on nock |
| Form | half-moon style nock fitted to Excalibur Quill arrows, indexed to the string | polymer clip that snaps onto the string, over an aluminium nock bushing |
| Fits | Excalibur Micro-series and TwinStrike crossbows shipped with Quill arrows | All Ravin crossbows except the R500 Series (R10, R18, R26, R29 and variants) |
| Compatibility rule | Excalibur ships Quill 16.5-inch arrows with a Rhino nock on the TwinStrike and Micro series. It is indexed like a half-moon nock and must be seated square to the string. | 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. |
