Abstract
A gun whose barrel ( ′) is connected to a breech ring ( ), and is seated to be displaced in a cradle barrel ( ). To prevent a lifting effect of the barrel ( ′) inside the cradle barrel ( ) upon firing, a slide-bushing bearing is disposed on at least the muzzle side of the barrel ( ′). The bearing encompasses a barrel bushing ( ′), in which the barrel ( ′) is disposed free from any lifting effect, and whose outside surface ( ) slides in a form-fit (i.e., with the smallest possible amount of play) in the cradle barrel ( ), so that the barrel ( ′) is independently guided to slide both axially and radially. The radial sliding guidance of the barrel ( ′) during firing is effected by tab-shaped protrusions ( ′), which extend into corresponding, groove-shaped recesses ( ′) of the barrel bushing ( ′) and hold the barrel ( ′) in the center of the barrel bushing ( ′).
