AMS Lighted Nocks
AMS Bowfishing® H2Glo Lighted Nocks fit only AMS Tiger Shark arrows. To use, just pull out the replaceable nock that comes with the arrow and insert the H2Glo nocks. Nock will automatically light up red when the arrow is released. A small switch on nock turns it off when not in use to save on battery. 3-pack.
