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.
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 ...
Reflector sights as aircraft gun-sights have many advantages. The pilot/gunner need not position their head to align the sight line precisely as they did in two-point mechanical sights, head position is only limited to that determined by the optics in the collimator, mostly by the diameter of the collimator lens.
1P78 is a telescopic sight manufactured by Novosibirsk Instrument-Making Plant and in use with the Russian Armed Forces, intended as a replacement for the older PSO-1 and 1P29 scopes currently being used by the Russian military.
M145 Machine Gun Optic fitted to a M240B machine gun. The M145 Machine Gun Optic is a variant of the C79 that was developed for the U.S. Army and is commonly mounted on M240 and M249 machine guns. The M145 is unusual when compared with other optical sights in use with the United States military in that ballistic compensation is in the mount ...
Red dots for rifles typically have a smaller dot, often 0.6 to 0.8 mrad (2 to 3 MOA). When red dot sights started to appear at the practical shooting competition circuit in the 1990s, reticle sizes of up to 3, 4.5 or even 6 mrad (10, 15 or 20 MOA) were common in order to compensate for the lack of bright illumination. However, as red dot ...

Sights can be a simple set or system of physical markers that serve as visual references for directly aligning the user's line of sight with the target (such as iron sights on firearms), [3] or optical instruments that provide an optically enhanced—often magnified—target image aligned in the same focus with an aiming point (e.g. telescopic ...
