Captive bolt tool system for use in humane dispatch of livestock

A captive bolt tool system for use in humane dispatch of livestock, the tool system comprising

• a tool housing with a working end;
• a movable bolt having an end effector for stunning or dispatching livestock;
• an actuation mechanism disposed in the housing and operable to move the movable bolt between a retracted position and an extended position;
• and
• a first and a second subject adaptor interchangeably connected to the tool housing, the subject adaptors each having an attachment end that is selectively received on the working end of the tool housing and an outer operation end with a contoured end surface, the contoured end surface shaped so as to mate with an outer surface of a head of a particular species or type of livestock in a predefined area for humane dispatch;
• an operating distance being defined between the working end of the tool housing and the contoured end surface of the subject adaptor when the subject adaptor is received on the working end of the tool housing;
• wherein:
• the shape of the contoured end surface of the first subject adaptor is different than the shape of the contoured end surface of the second subject adaptor such that the first and second subject adaptors are configured for use with different livestock;
• or
• the operating distance of the first subject adaptor is different than the operating distance of the second subject adaptor such that an outermost end of the end effector of the movable bolt in the extended position protrudes by differing amounts when used with the first and second subject adaptors.
