A device is provided for establishing or releasing the coupling between an adjustment ring, which can be rotated on a base element by way of a detent mechanism and is provided with an adjustment shaft for optical elements, and a cylindrical index ring, which is inserted between the adjustment ring and the base element so as to rotate in relation to an index mark provided on the base element, wherein an inwardly directed ring surface is integrally formed on the edge of the index ring pointing toward the adjustment ring, at least one friction element under spring pressure is inserted between the adjustment ring and the ring surface, and the spring pressure can be removed by way of a pressure element inserted into the top face of the adjustment ring or by way of a lever mechanism.

A sight installation device, comprising a body having a notch which is capable of receiving a pistol slide with a sight receiving groove, the notch possessing a first and a second lateral sidewall, and an at least one horizontal brace abutment. The sight installation device's body also has at least one guide channel proximate the notch, in which a pusher bit is longitudinally slidable and configured so as to contact a sight element directly in line with the pistol slide's sight-receiving groove. The sight installation device also possesses a drive screw configured to engage an opening in the body proximate the guide channel, the drive screw engaging the opening and configured to engage the pusher bit.

A novel and improved rotating stock butt and rotating sight apparatus that applies to a shoulder fired firearm where the firing mechanism and the sight apparatus is elevated above the stock butt when in a horizontal shooting position. This system comprises a cooperation between the rotating stock butt and the rotating sight apparatus that allows the firing mechanism and the barrel of the firearm to be off set to either the right or to the left of the stock butt while the sight of the rotating sight apparatus can be rotated and secured at the top center of the firearm barrel, allowing the shooter minimal head movement in the gun mount.

A device for supporting scopes, such as telescopes, holographic, laser, red-dot aiming systems, etc., for rifles equipped with rib, is described. The device comprises a body, on which the scope can be fastened, and a plurality of claws slidably mounted on the body. The claws are movable to be opened and closed in response to the displacements imparted by the user to corresponding thrust elements, through a special adjusting grub screw. The body has a longitudinal axis which is aligned with the optical axis of the scope mounted thereon each time. The displacements of the thrust elements take place along the longitudinal axis, while the displacements of the claws take place toward and away from the longitudinal axis, in a direction orthogonal thereto. The device is self-centring, meaning that the claws are closed on the rifle rib, so that the latter is always aligned precisely on the longitudinal axis.
