Excalibur Proflight 16.5: the crossbows it fits
The published spec of the Excalibur Proflight 16.5, the nock it uses, and the crossbows it fits.
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.

The Proflight is Excalibur's 16.5-inch carbon arrow for all Micro crossbows, close in weight to the Quill but at a tighter straightness.
It is a flat-nocked arrow for the Micro recurve rail, so it is not interchangeable with a captured or clip-on nock from another brand.
As with all Excalibur Micro arrows, stay above 350 total grains.
