Available in 18 colors / shades (3 nock colors x 6 LED colors)

Full system, on average, weighs only ~31 grains

    Firenock products are very well made products. I decided to try the D3 nocks out of my Excalibur for the full containment. I use Q nocks out of my Scorpyd. These nocks fit perfect and are very accurate. I will shoot these from my Excalibur from now on.
