Abstract: An improved automatic loading cross-bow comprising a main frame having pivotally mounted interchangeable bow limbs adjacent to its front end. The bow limbs can be latched in a folding position, for easy transportation, in an extended position for firing, or can be interchanged for different bow weights. The cross-bow includes an arrow magazine containing a plurality of arrows adapted to be attached to the main frame. An improved spring device automatically feeds arrows, one at a time, into the firing position in the main frame as the bow string is cocked. An improved safety release trigger is adapted to be cocked by moving the bow string into firing position and to be fired only when the safety release and trigger are both actuated. The improved release trigger further provides for a smooth center line firing.
