Abstract

A crossbow cocking system may include a sled having first and second arms, an elongated cocking cable, a first handle, a second handle, a first engagement feature and a second engagement feature. The first and second engagement features may be used to engage the first handle to the first arm and the second handle to the second arm, respectively. Each engagement feature may include at least one cavity and at least one protrusion that is received in the cavity for engagement. The handles may be disengaged to permit a user to cock the crossbow.
