Abstract

A crossbow includes a body having a stock member and a barrel connected to the stock member. The barrel has an arrow receiving area for receiving an arrow. The crossbow also includes a bow having a pair of bow arms, a bowstring connected to the bow arms, a bowstring release mechanism used to hold and release the bowstring and, a scope mount used to hold a scope. An arrow retention spring is provided for retaining the arrow to the arrow receiving area. A vibration dampener may be positioned between the arrow retention spring and the scope mount in order to dampen the arrow retention spring vibrations made when shooting the crossbow. This greatly reduces unwanted noise.
