J Style Firenock Replacement Nock (7/14/100)

Firenock "J" was initially designed as the "big brother" of the "Q" nock in 2013. Unfortunately, crossbows at the time had trigger boxes that did not allow for a long-prong design. Therefore, the short prongs were born and awarded a US design patent (D171389).

The "J" style nock was developed to fit railed crossbows with a 0.151" to 0.157" center serving, and non-railed crossbows with a 0.157" to 0.162" center serving, arrows with a 0.300" ID, and triggers / anti-dry-fire (ADF) systems that require a short-pronged design.

Available in 18 colors / shades (5 nock colors x 6 LED colors)

Full system, on average, weighs only ~31 grains
