Nocks & Components

Lighted nocks, replacement nocks, circuits, batteries and outserts, all from Firenock, the most engineered lighted-nock system in archery.

Firenock runs two nock diameters, .166 and .204, and they aren't interchangeable: buy the one that matches your shaft's actual inside diameter, not the one that matches a friend's setup. A lighted nock adds real weight to the back of the arrow, more than a standard nock, and rear weight stiffens dynamic spine. That means a shaft that was properly spined with a field-point nock can shoot slightly different once a Firenock hunting circuit goes in the back. It's a small shift, but a real one, and it's the kind of thing that turns into an unexplained flyer at 40 yards if you skip checking it.

The upside is real too. A lighted nock is the difference between finding a marginal hit at last light and not finding it at all, which is most of the reason bowhunters run them despite the extra cost and the extra step.

Before you install one, re-run your spine with the added rear weight, and see which lighted nocks actually hold up in the field.
