Abstract: A cocking system for retracting a string carrier on a crossbow that is substantially silent during operation. The cocking system includes a string carrier with a catch that is moveable between a closed position that engages a draw string, and an open position that releases the draw string. The string carrier slides along a center rail between a released configuration and a retracted position that locates the draw string in a drawn configuration. A trigger is positioned to move the catch from the closed position to the open position to fire the crossbow when the string carrier is in the retracted position. The cocking system includes a retaining mechanism that retains the string carrier in the retracted position while permitting a draw string to disengage and fire an arrow.
