Drehvisier rotating drum sight pictures. The firearm is equipped with a relatively low iron sight line that consists of a Drehvisier a rotary rear drum and hooded front post. The rear sight is mechanically adjustable for both windage and elevation with the help of tools. This deliberately prevents non-armorers to (re)zero the iron sight line.
With tangent sights, the rear sight is often used to adjust the elevation, and the front the windage. The M16A2 later M16 series rifles have a dial adjustable range calibrated rear sight, and use an elevation adjustable front sight to "zero" the rifle at a given range. The rear sight is used for windage adjustment and to change the zero range.

The AR-15 rifle has a 500 mm (19.75 inches) sight radius. The AR-15 uses an L-type flip, aperture rear sight and it is adjustable with two settings, 0 to 300 meters and 300 to 400 meters. The front sight is a post adjustable for elevation. The rear sight can be adjusted for windage. The sights can be adjusted with a bullet tip or pointed tool.
The sight line radius is 602 millimeters (23.7 in). The MG5 was expressly designed to use various types of receiver mounted optical sights as its primary sighting option. Therefore achieving a negligible zero change in practical use between barrel assembly changes was a major design requirement that was not easily met.
