The Beiter InOut - Nocks fits precisely into the shaft and preserves the shafts end with the bigger outer diameter.
The InOut -Nock is available only for selected Aluminum Carbon shafts, both in the Beiter patented ASYMMETRIC version, as well as in the SYMMETRIC type, for Compound archers using a D - Loop.
Each Nock size has only one single mould.
This offers highest precision and lowest tolerances.
Every single InOut - Nock comes out of the same cavity.
