Upgrade your Mission Crossbow setup with the Removable Silent Draw (RSD) Crank! This accessory installs in a matter of seconds thanks to a cam-lock bar, and makes cocking the crossbow 25x easier. Operation is completely silent, and the operator can safely stop/resume the cocking process at any point. In addition, the RSD is ambidextrous and is compatible with all crossbow models offered my Mission. Mission RSD Crank Aid 80770
