Since their invention in 1900, reflector sights have come to be used as gun sights on various weapons. They were used on fighter aircraft, in a limited capacity in World War I, widely used in World War II, and still used as the base component in many types of modern head-up displays.
Reflector sights were first used as a weapon sight in German aircraft towards the end of World War I. Over the years they became more sophisticated, adding lead computing gyroscopes and electronics (the World War II Gyro gunsight ) [ 8 ] radar range finding and other flight information in the 1950s and 1960s, eventually becoming the modern head ...
Standard doctrine with iron sights is to focus the eye on the front sight and align it with the resulting blur of the target and the rear sight; most shooters have difficulty doing this, as the eye tends to be drawn to the target, blurring both sights. Gun users over 30 years of age with keen eyesight will find it harder to keep the target ...
The PE scope (Russian: Винтовочный оптический прицел образца 1931 г. [1] or ПЕ, often called Прицел Емельянова, or Yemelyanov's sight [2] or Прицел Единый or Standard sight) is a family of Soviet telescopic sights, used from 1930s onwards on Mosin-Nagant sniper rifles, as well as SVT and AVS rifles.

This new sight became the Mark II Gyro Sight, which was first tested in late 1943 with production examples becoming available later in the same year. Ferranti built a new factory in the Crewe Toll area of Edinburgh, Scotland to build the sights. This factory would later go on to be the center for Ferranti's long history in radar development.
Tang sights were mounted behind the action of the rifle, and provided a very long sight radius, and had to be unfolded for use, though rifles with tang sights often had open sights as well for close range use. Tang sights often had vernier scales, allowing adjustment down to a single minute of arc over the full range of the sight.
The Ross rifle was a straight-pull bolt-action .303 calibre rifle produced in Canada from 1903 until the middle of the First World War, when it was withdrawn from service in Europe due to its unreliability under wartime conditions, and its widespread unpopularity among the soldiers. Since the Ross .303 was a superior marksman's rifle, its ...
PU telescopic sight from above. The PU scope (ПУ, прицел укороченный, 'Scope short-cut' in comparison to PE/PEM telescopic sight) is a 3.5×21 telescopic sight of Soviet manufacture, widely used since 1940 on the SVT-40 rifle for which it was originally designed and since 1942 on the Mosin–Nagant rifle.
