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.

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 M1873 Colonial Rifle was developed for deployment to the Dutch East Indies. The rifles replaced earlier percussion rifles and centerfire rifles created by Lt. FWH Kuhn. Earlier shipments of the rifle were sent back to Europe due to the rear sights not having distance markings. In total, 35,000 rifles were produced for deployment to the colony.
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 ...
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 ...
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.
Soon after, nations all around Europe began adopting breech-loaders and converting their existing service rifles to breech-loaders. Such rifles include the British Snider Rifle and the French Chassepot Rifle. These new rifles, along with the invention of the revolver (patented in 1836) and the advent of machine in the 1860s, displayed the need ...
