Tenpoint Alpha Blaze Light Nock HP Bushing

The Alpha-Blaze Lighted Nock contains a one-piece Nock/LED unit that is indexed with the vanes and press fits into the arrow’s Aluminum Bushing. It has a super bright LED that provides superior arrow flight visibility to track your shot’s point-of-impact and lasts approximately eight hours when activated. Activated by the bowstring's force when firing and can be deactivated by pulling the nock out until the light turns off.
