    摘要: Adjustable-caliber rod apparatus for testing and adjusting weapon barrels. The rod is used for representing the barrel bore axis in conjunction with, e.g., a sight-line testing device for adjusting sights. The rod has two three-point supports, two support points of which are pressed against the inner wall of the barrel by a third, spring-loaded mounting point. This leads to a forced orientation of the caliber rod, so that the axis thereof is aligned parallel to the barrel bore axis. Each support assembly has a fixed flange and an adjustable flange which is adjustably guided on the fixed flange. Locking devices are provided for locking the adjustable flange relative to the fixed flange, and detents between the adjustable and fixed flanges facilitates reproducible setting to specific barrel calibers.
