Image Number 7 for United States Patent #4617750.
An annularly symmetrical multiple fire weapon having a unitary tubular barrel with a series of annularly arranged, regularly spaced firing bores and respective cartridge chambers therein. The unitary tubular barrel means is suitable for mounting of an optical scope coaxially in the throat thereof. A firing pin release system in the weapon is incrementally rotatably shiftable in firing pin release increments to sequentially fire either one of the bores at a time or diametrically opposed pairs of the bores simultaneously. The firing bores are pre-loaded prior to a multiple fire sequence, as distinguished from the continuous loading during a firing sequence of an automatic weapon.
