Crossbows are known for firing bolts at blazing speeds.  So fast, sometimes, that it's difficult to track the arrow in flight.  Nockturnal Lighted Nocks have remedied this problem with their new nock designed for crossbow bolts.

As the popularity of crossbow hunting continues to grow, it is no surprise that Nockturnal Lighted Nocks is leading the way with a series of new Crossbow Lighted Nocks with an exclusive patent-pending Universal Fit Technology™, that allows the Nockturnal nocks to fit virtually any crossbow bolt. With the Universal Fit Technology and three nock configurations-half-moon, capture and flat-back-consumers don't have to worry about which nock to use with their bolt or crossbow, they simply need to order the Nockturnal Lighted Crossbow Nock of their choice.

As with all the Nockturnal Lighted Nocks, the crossbow nocks require no assembly. They can go straight from the package to the bolt in full operation condition. The piston-driven contact switch is hidden and protected to prevent inadvertent activation or deactivation of the L.E.D. illumination. With a lithium battery life of more than 20 hours, you can still find your arrow the next day if you need to.
