These nocks are constructed of tough polycarbonate material with a press-fit design. Their double-snap throat keeps arrows on the bowstring, even at extreme angles. Per 12.
Colors: Fluorescent Green, Fluorescent Orange, White, Yellow.
I have split the nocks in several of my Cabelas Carbon Hunter Arrows. (I shot them with another arrow.) These are the same nocks Cabela's uses in the manufacture of these arrows. Thus, they are the perfect replacements.
