TenPoint Alpha-Blaze HPX Lighted Nock for HP Bushing

The Alpha-Blaze HPX Lighted Crossbow Nock (3-pack) provides bright, reliable illumination to help archers and target shooters track and recover arrows in low-light and after-shot conditions at the range or during practice. Each one-piece Nock/LED unit is indexed with the vanes and press-fits into an HP aluminum bushing (bushing and arrow sold separately), so there is no assembly required-install and shoot. This 3-pack of red HPX nocks weighs 27 grains each and offers approximately 24 hours of LED runtime when activated. Activation is automatic: the bowstring's force compresses the unit on firing to turn the light on, and you deactivate it by pulling the nock straight out until the light goes off. A dedicated nock retention groove provides audible and tactile engagement on TenPoint rail-less crossbows, ensuring confident seating on the string. These Alpha-Nock HPX units are designed to fit all TenPoint and Wicked Ridge arrows that use the HP aluminum bushing; note that TenPoint & Wicked Ridge crossbows require the use of an Alpha-Nock and that HP aluminum bushings and arrows are sold separately.
