Abstract: A gun in which the gun barrel (2) is seated to be axially displaced in a cradle barrel. To avoid a lifting effect of the gun barrel (2) upon firing, and omit the necessity of complicated guide grooves in the cradle barrel (3) and tabs on the gun barrel (2), an elastically deformable, first slide-bushing bearing (5) is provided at the muzzle end of the cradle barrel, and a second slide-bushing bearing (6) with a predetermined amount of fit play is provided at the breech-ring end of the cradle barrel 3.

Abstract: A gun whose barrel (2′) is connected to a breech ring (16), and is seated to be displaced in a cradle barrel (3). To prevent a lifting effect of the barrel (2′) inside the cradle barrel (3) upon firing, a slide-bushing bearing is disposed on at least the muzzle side of the barrel (2′). The bearing encompasses a barrel bushing (7′), in which the barrel (2′) is disposed free from any lifting effect, and whose outside surface (8) slides in a form-fit (i.e., with the smallest possible amount of play) in the cradle barrel (3), so that the barrel (2′) is independently guided to slide both axially and radially. The radial sliding guidance of the barrel (2′) during firing is effected by tab-shaped protrusions (10′), which extend into corresponding, groove-shaped recesses (9′) of the barrel bushing (7′) and hold the barrel (2′) in the center of the barrel bushing (7′).

Abstract: A tank turret including an armored turret housing having a front side provided with solid front armor, and a pivotally mounted gun including a cradle shield, cradle, recoil device and rearward breech block housing being arranged in the turret housing. The armored turret housing, or at least parts of it, are used to increase recoil mass of the gun.
