摘要： A crossbow may include a crossbow barrel having reduced weight and increased strength and shock resistance to the crossbow. This invention may also aid in improving torsional resistance, improving specific stiffness, and increasing compresses strength. The invention may also reduce friction between a barrel and a bow string to increase bow string life. The invention may also reduce the friction between a barrel and a bow to allow added arrow distance. Additionally, the crossbow may decrease both vibration and sound.
