QAD Tune A Nock Glue On. The Tune-A-Nock is the fastest nock on the planet! 360 degree rotation provides precise fetching to arrow rest adjustment. Short ear design provides cleaner release from bowstring, improving accuracy. Low-friction string groove increases arrow speed 2 1/2 second on average.
The first ever glue on arrow nock that is tunable and replaceable without re-glueing. Flared opening allows easy guidance of arrow onto bowstring. Works best with the Ultra-Nock but is compatible with brass nocks and virtually any bow set-up. Compatible arrows: Fits swaged taper shafts 19xx or larger.
