The Nockturnal 22 Inch Lighted Crossbow Bolts come installed from the factory with a Nockturnal Predator Lighted Nock. Designed specifically for today's high speed crossbows, this lighted nock utilizes a durable plunger design that reliably activates at the shot and a lithium battery which provides 20+ hours of run time allowing you to find your arrow even the following day. Now you can see your impacts and quickly retrieve your fired arrows, making you a better and more efficient hunter. This nock is designed to function as a half moon, capture and flat nock all in one.
Shoot it at dusk, and with more than 20 hours of battery life, you can still find your arrow the next day. Nocks can go straight form the package to the shaft in fully operational condition. No prep work needed. Just insert it, and you are ready to shoot. Piston driven contact switch ensures L.E.D. illumination every time. Waterproof and shock resistant design is second to none.
