CenterPoint Carbon Arrows are built to handle the high energy of modern crossbows and come equipped with preinstalled half-moon nocks for consistent string-to-nock contact. Each durable carbon shaft is fletched with 2-inch Blazer vanes and held to a 0.003-inch straightness tolerance for repeatable accuracy. These 20-inch arrows weigh 400 grains when paired with a 100 grain field point (sold separately) and are intended for crossbows that use 20-inch bolts.
