Moon nocks or flat nocks. What kind of nock should I shoot? The correct answer is whatever your crossbow manufacturer recommends. There is however, one exception to the rule. If your crossbow manufacturer recommends you to shoot flat nocks, it will not hurt your crossbow to shoot an arrow with a moon nock. On the flip side, if your crossbow manufacturer recommends you to shoot moon nocks, you do not want to shoot flat nocks. Flat nocks fired from a crossbow that requires moon nocks may result in a partial dry fire of your crossbow. This is because the string can jump over the flat nock, whereas the moon nock keeps the string centered in the back of the arrow, the full length of the power stroke. Please make sure to read your owners manual and use the recommend nock.
