A mechanism, which may be integral with the gun parts and which permits the butt of a shouldered firearm, that either shoots shot or projectiles, to be pivoted about an axis, or which is integral to the gun parts whereby the stock butt is pivoted by design and fixed in place, or which may be manufactured as an after-market item, and which permits the butt of a shoulder-fired gun to be pivoted about a central point. This final design only applies to any shouldered firearm where firing mechanism, barrel, and sighting device are elevated above stock butt. |

1. A shoulder-fired firearm comprising:
a firing mechanism, a barrel, a sighting bead, a rotating stock butt, the rotating stock butt including a grip, a cheek weld and a recoil pad below the top longitudinal surface of the firing mechanism, barrel and sighting bead when the shoulder-fired firearm is in a horizontal firing position, all descriptions hereafter are written to this orientation; the rotating stock butt, having a first and second member, which provides an axis for rotation, the axis substantially parallel with the barrel, the first member having a first leading end and a second trailing end and the grip, the first leading end fastens to a rearward trailing end of the firing mechanism, the second trailing end extends rearward from the firing mechanism, aligning substantially parallel with the firing mechanism and the barrel; the second member of the rotating stock butt, having a first leading end and a second trailing end, a first upper portion and a second lower portion; the first leading end and the first upper portion having an elongated opening that extends rearward from the first leading end reducing in size and exits out the second trailing end of the first upper portion of the rotating stock butt; the second trailing end of the first member of the rotating stock butt is housed within the elongated opening of the second member of the rotating stock butt, and configured to allow rotation between the first and the second members of the rotating stock butt; a series of removable spacers, having central openings, are placed in the elongated opening in the first upper portion of the second member of the rotating stock butt; wherein a length of the rotating stock butt from the firing mechanism is determined by the number of the spacers used; the second trailing end of the second member of the butt stock includes the recoil pad; wherein the recoil pad is attached to the second trailing end of the second member of the rotating stock butt. |
