Beiter .166 Asymmetric Insert Nock

The Beiter .166 Asymmetric Insert Nock is a precision-engineered push-in nock designed for arrow shafts with a .166” internal diameter. Manufactured to the exacting standards that Beiter is known for, this nock delivers consistent fit, reliable performance, and excellent durability for competitive and recreational archers alike.

Its asymmetric design is particularly suited to recurve and barebow archers who release the string with their fingers rather than a mechanical release aid. Because the string does not leave the fingers symmetrically, an asymmetric nock helps the arrow depart the bowstring in a cleaner and more controlled manner, promoting improved arrow flight and enhanced consistency downrange.

The Beiter .166 Asymmetric Insert Nock is compatible with many popular aluminium-carbon and carbon target shafts that accept a G-Nock style fit. For proper installation and performance, the Beiter logo should always face upwards.
