Bolt length, nock type and minimum grain weight are quoted from each manufacturer's published arrow data and owner documentation, cited on every page. A nock 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 before shooting, and never drop below the stated minimum total grain weight.

The Vapor RS470 is a fast reverse-draw TenPoint, 6.5 inches narrow, matched to the 20-inch EVO-X CenterPunch carbon arrow with an Alpha-Nock. At 470 fps the arrow and nock are a tuned system.
At 470 fps a wrong or mis-indexed nock is the fastest route to a dry-fire. Keep the CenterPunch arrow and its Alpha-Nock and never drop below the shipped grain weight.
