Abstract: A tilt-equalization arrangement for steep angle firing guns. The barrel of the gun has secured to its rear end a ball pin which is swivelably mounted within a ball socket. The ball socket is secured to a base plate. Forwardly of its rear end the barrel is provided with at least one longitudinally adjustable aligning post. The aligning post is slidably movably mounted on a circular ring segment forming a guide rail for the aligning post. This guide rail is vertically adjustable at its opposite ends so that it forms an adjustable leveling plane for the aligning post, with the ball pin forming a fixed support point and also being situated at the center of the circular ring segment forming the guide rail.
