Replacement Nock 10pcs for Aluminum 30 inch Arrow Bolts

The nock serves to keep the arrow in place on the string as the bow is being drawn. Our Nock are made from hard Red ABS plastic and is made to fit the 30 inch Aluminum Arrows. It features a U shape head which is red in color and fits perfectly on the string or cable. The red nocks are just tight enough to keep the shaft on the string, without affecting your release at time of shooting.
