Abstract: A firearm sighting device having a base, a first sighting lever arm pivotable relative to the base around a first pivot axis, a second sighting lever arm pivotable relative to the base and first sighting lever arm around a second pivot axis, a rear sight device fixed on the second sighting lever arm, a first positioning device for adjusting a pivot angle of the first sighting lever arm relative to the base, and a second positioning device for adjusting a pivot angle of the second sighting lever arm relative to the first sighting lever arm and the base. A rotating positioning element on the first sighting lever arm includes alignment elements that each have a positioning tip so that a distance between the positioning tip and rotating positioning element is adjustable. A buttress element on the bottom of the base interacts with the positioning tips.

Abstract: A barreled firearm having a mass-locked breechblock and a recoil-damping element which is connected on one side to a frame assembly and on another side to a barrel assembly including a barrel. A housing part of the barrel assembly is mounted in the frame assembly in an axially slidable manner. A support element stationary relative to the barrel is mounted in a breechblock housing or in the frame assembly in an axially slidable manner. Alternatively, a support element stationary relative to the frame assembly is mounted in a breechblock housing in an axially slidable manner. The breechblock housing is guided by the frame assembly in an axially slidable manner and the breechblock housing is supported by the support element by means of a spring element. This design absorbs or reduces recoil when a shot is fired from the barreled firearm.

Abstract: A sight device for a firearm having a base, a sight arm, a rear sight slide, and at least one rear sight piece having a rear sight. The sight arm engages the base and is pivotable in a pivot direction relative thereto about a pivot axis. The rear sight slide, arranged proximate a free end of the sight arm, is displaceable relative to the sight axis and the pivot direction relative to the sight arm, and is fixed on the sight arm in an adjusted setting position. The rear sight slide includes a receptacle with retaining structures for removably engaging the rear sight piece. A latch section of a spring-loaded latch piece on the rear sight slide engages in a latch receiver on the rear sight piece when the rear sight piece is inserted into the receptacle and holds the rear sight piece in a fixed position.
