Abstract
In a device for carrying out quality test firings with a gun barrel (1), a mount (2) and an automatic adjusting arrangement (4, 5, 6) for resetting the barrel (1), a given directional setpoint value is compared with the actual direction value. While the actual value is derived from a mirror (3) attached to the barrel (1) itself, the setpoint value is produced by a frequency-modulated laser beam (.nu.) from a source mounted nonvibratingly and separately from the barrel (1) and its mounting (2). By this separation, the hit dispersion due to the mechanical components is reduced to a minimum. This device is of particular usefulness in the development and quality control of small-calibre ammunition.
