Firenock “D3” was made for those who own crossbows that not only require a 0.165” serving, but need a shorter head to compensate for a trigger box. This nock is practically identical to the “D2” nock except for its stubbier prongs.
To fit crossbows with a 0.165" serving and arrows with a 0.300" ID with triggers / anti-dry-fire (ADF) systems that require a short-pronged design.
Available in 18 colors / shades (3 nock colors x 6 LED colors)
Full system, on average, weighs only ~31 grains
Ready for the only target lighted nock system that is IBO & ASA approved: Firenock “T” circuit
Ready for hunting and intermittent lighted nock systems that stay lit / blink for up to 21 days with a BL battery powering a Firenock “H” / “I” red circuit
D3 Style Firenock
Perfect fit for Excalibur Cross Bow
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.
