Beiter Insert Nock (.204): https://bit.ly/48UDEGR
New for 2024, Beiter has reintroduced its former 5-19 nock as the .204 Insert Nock for arrows with an inside diameter of .204 inches or 5mm. The nock is available in Asymmetrical #1 and #2 and Hunter configurations. As always, all Beiter nocks of the same variety come from a single mold for supreme consistency.
