specs differ
Barnett capture nock and Half-moon nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Barnett capture nock | Half-moon nock |
|---|---|---|
| Nock | HyperFlite capture nock | half-moon (moon) nock |
| Form | positive capture nock that snaps onto the string, small-diameter.204 in shaft | shallow concave groove across a flat disc; must be indexed to the string |
| Fits | Barnett Hyper series only (HyperFlite, HyperGhost, HyperTac 420/430, Hyper Whitetail 410) | CenterPoint, most Barnett non-Hyper models, and many entry and mid crossbows |
| Compatibility rule | The.204-inch HyperFlite is a small-diameter arrow with a capture nock made only for Barnett's Hyper-series crossbows; a standard-diameter Headhunter arrow will not fit the Hyper rail. | 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. |
