Ravin Crossbows Premium Arrows HD Features The Ravin Crossbows Premium Arrows HD are built from 100 percent pure carbon construction and held to a .001 inch straightness tolerance a precision level that keeps group sizes tight shot after shot. At a 500 grain weight these arrows are matched for consistent downrange performance and dependable energy transfer on impact. High-impact threaded brass inserts let the arrow accept broadheads and field points securely while standing up to the repeated stress of impact without loosening. A high-impact aluminum nock bushing reinforces the rear of the shaft protecting against the sharp jolt of the bowstring at the moment of the shot. Each arrow uses a polymer nock paired with 2 inch high-profile offset vanes a combination built to stabilize the arrow quickly in flight for better accuracy at distance. The arrows ship in a 6-count pack at 20 inches in length finished in Black for a clean low-glare look in the field. These arrows are intended for use only with Ravin-branded arrows and Ravin clip-on nocks and are not compatible with the Ravin R500 crossbow. The Ravin Crossbows Premium Arrows HD are for sale at GrabAGun for Ravin crossbow owners who want a dedicated match weight arrow built to the same tolerance every time.
