TenPoint’s ACU-X Lighted Snap-On Nock & Alpha-Blaze Lighted Nocks contain a onepiece Nock/LED unit that is indexed with the vanes & press fits into the arrow’s Aluminum Bushing. Upon firing the crossbow, the bow string pushes the nock fully into the bushing & activates the LED light.
Deactivate the easy on/off lighted nock by pulling the nock straight out until the light turns off. The LED light system lasts for approximately 24 hours when activated. Use of the Bednar Perfect Puller 2.0 makes lighted nock deactivation extremely easy.
The lighted nock fits into TenPoint & Wicked Ridge arrows equipped with an HP Aluminum Bushing (sold separately)
The ACU-X Snap-On Nock features our innovative Snap-On design, providing an unmistakable audible “click” when properly engaged with the bowstring, eliminating lateral nock travel during the shot cycle for precision long-range accuracy, while preserving string center serving life.
The ACU-X Snap-On Nock provides secure string fit & the most consistent design for rail-less crossbows.
NOTE: The ACU-X Snap-On Nock is required for use with TenPoint Rail-Less Crossbows. Failure to do so will void the manufacturer’s warranty.
