specs differ
Barnett capture nock and Flat nock differ on 4 specs: nock, form, fits, compatibility rule.
| Spec | Barnett capture nock | Flat nock |
|---|---|---|
| Nock | HyperFlite capture nock | flat (flat-back) nock |
| Form | positive capture nock that snaps onto the string, small-diameter.204 in shaft | plain flat disc on the shaft base, non-indexed |
| Fits | Barnett Hyper series only (HyperFlite, HyperGhost, HyperTac 420/430, Hyper Whitetail 410) | Excalibur Micro series and older recurve 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 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. |
