Adjustable sighting device for a small arm

Abstract

The invention concerns an adjustable sighting device for a small arm, in particular, for a shotgun, with a rail body ( 3 ) that can be fixed on the barrel ( 1 ) or the barrel group of the small arm, and a sighting device ( 4 ) which is arranged in an adjustable manner on the rail body ( 3 ). In order to obtain improved adjustment possibilities, the sight rail ( 4 ) is adjustable in height relative to the rail body ( 3 ) at both ends, by means of adjusting elements ( 6, 13 ).
