Abstract

An improved arrow has an arrow shaft having a first diameter, a first end defining a tip and a second end defining an area that interacts with the string of a crossbow. A first ring is formed proximate the first end of the arrow shaft and has a second diameter and a first length. A second ring is formed proximate the second end of the arrow shaft and has a third diameter and a second length. In various embodiments, the second and third diameters are larger than the first diameter of the arrow shaft and may be equal. The first and second rings function to allow the arrow to be shot from a crossbow having a barrel to reduce the amount of friction that exists between the arrow and the barrel walls and to reduce the amount of noise generated as the arrow traverses and exits the barrel.
