Abstract
A breech block has, for each cheek of a breech ring, at least one bearing surface facing a rear of the breech. The bearing surface is adjustable to slide along a paired bearing surface of a matching bearing element of the cheek and bears on the paired bearing surface to transfer strain to the cheek generated during firing of a round. The bearing surface of the breech block and the paired bearing surface of the cheek of the breech ring face each other so that the plane of each of the matched bearing surfaces intersects a plane defined by the axis of the barrel and a horizontal line along a half-line terminating at the axis. The half-line defines an angle greater than 90.degree. with respect to the axis.
