Excalibur Rhino nock: which crossbows use it
Where the Excalibur Rhino nock is used, its shape, and the compatibility rule that stops a dry-fire.
Dry-fire warning
Crossbow bolt data and archery arrow spine, nock and thread data are quoted from each manufacturer's published figures, owner documentation and industry standards, cited on every page. A nock, spine or grain-weight mismatch can cause a dry-fire that damages the bow and can injure the shooter. Confirm against your own owner's manual and the arrow maker's own chart before shooting, and never drop below the stated minimum total weight.

Field notes
Used on: Excalibur Micro-series and TwinStrike crossbows shipped with Quill arrows.
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.
A Rhino nock is a moon-style nock, so it must be indexed. Loaded a quarter-turn off, the string can ride the rim of the groove and dry-fire the bow. Seat the odd vane where the manual shows.
