Abstract
An ammunition indexing mechanism for moving, responsive to actuation of a trigger mechanism, a cartridge from a selected one of a pair of opposed feedports in a weapon receiver and into alignment with a firing chamber of a barrel assembly of the weapon, has a rotary mechanism for moving through a selected index angle each ammunition cartridge entering through the selected feedport; and a torque assembly for storing energy, responsive to a selected movement of the barrel assembly, until released to operate the rotary mechanism to move, for each selected barrel assembly movement, each sequential cartridge through similar angular displacement to a position aligned with the firing chamber.
