TenPoint ACU-X Lighted Nocks for HP Bushings

Super bright for superior visibility, the ACU-X Snap-On Lighted Nock contains a one-piece Nock/LED unit that is indexed with the vanes and press fits into the arrow’s Aluminum Bushing. Upon firing the crossbow, the bowstring’s force compresses the two pieces and activates the lighted nock. Deactivate the easy on/off ACU-X Snap-On Lighted Nock by pulling the nock straight out until the light turns off.
