Guarantees consistent string alignment for best accuracy
Minimal effort required to cock any current model crossbow (These are the 2008 and newer stocks, either with the thumbhole, or 5 diagonal slash marks located on either side of the trigger, also fits the Vixen II)
Detaches in seconds, removing unnecessary weight from the crossbow unlike permanently mounted cranks
Constructed of high-strength light-weight aluminum alloys to reduce weight
Machined to the tightest tolerances to provide years of trouble-free service
