Two adjustment knobs are used to secure the base to the receiver. A bore-sighting device is usually used to roughly zero the sight before a first-time shooter takes it to the range. Adjustments come in 0.25-mil clicks (one mil equals 10 cm at a range of 100 m, so each click adjusts the sight by 2.5 cm at 100 m). Sighting in a C79 sight is ...
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 diopter sight is easy to use and usually allows for very accurate aiming, because a relative long sighting line can be used. A long sighting line helps to reduce eventual angle errors and will, in case the sight has an incremental adjustment mechanism, adjust in smaller increments when compared to a further identical shorter sighting line.
Telescopic sights for use on light-recoiling firearms, such as rimfire guns, can be mounted with a single ring, and this method is not uncommon on handguns, where space is at a premium. Most telescopic sights are mounted with two rings, one in the front half of the telescopic sight and one on the back half, which provides additional strength ...
Mark III free gun reflector sight mk 9 variant. Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view.

6. Adjust the bore angle by the angle correction. The gun sight is adjusted up by 0.94 mil or 3.2' in order to compensate for the bullet drop. The gunsights are usually adjustable in unit of 1 ⁄ 2 minutes, 1 ⁄ 4 minutes of angle or 0.1 milliradians.
While MOA sights have traditionally been popular in the U.S., scope sights with mrad adjustments and reticles are now also becoming increasingly popular in the U.S. [14] The most common reticles used today in red dot sights both for handguns and rifles are small dots covering between 0.6 and 1.6 mrad (2 to 5 MOA).
Reflector sights consisting of a 45-degree angle glass beam splitter that sat in front of the pilot and projected an illuminated image of an aiming reticle that appeared to sit out in front of the pilot's field of view at infinity and was perfectly aligned with the plane's guns ("boresighted" with the guns). The sight sat some distance away ...
