A launcher which can be readily converted for use by either a right-handed or left-handed shot. The launcher has a receiver with upper and lower extensions extending forwardly from the receiver body. A barrel is pivotally mounted near forward portions of the extensions, in one of two positions, such that in one position it is pivotable from a home position aligned with the receiver and the extensions between the two extensions, to a load position with the breech of the barrel to the left, and such that in the other position it is pivotable from the home position, to a load position with the breech to the right. One way of accomplishing this is with a barrel support bracket to which the barrel is pivotally mounted, with the barrel support bracket being secured at or near the front of the receiver extensions, and being rotatable between two positions, each corresponding to a different swing direction for the barrel.
