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 Micro Suppressor is a quiet Micro-series Excalibur recurve at 355 fps, using the short 16.5-inch flat-nocked Quill arrow. It pairs the Quill best with a 150-grain point to stay above the minimum weight.
Do not fit a 20-inch or captured-nock arrow. The Micro rail centres the string on a flat nock; keep the short Quill or Proflight and stay above 350 total grains.
