Sighting device record
Nov 12, 2017

It has been written that, before 19th century, the firearm had a telescope-type sighting device that could be used to target under weak light conditions. By the 1840s, some American gun technicians began to manufacture firearms with optical sights. The 1848 New York State Morgan James designed a tubular sighting device of the same length as the barrel, with a glass lens in the back half of the device and 2 cross lines for aiming. Later, similar sighting devices were used in the American Civil War. But the real practical value of the sight, was born in 1904, developed by the German Carl, and used in the First World War. In the Second World War, the aim mirror began to mature. 

Development to now, the aim of the mirror is divided into the following three main categories: telescopic sight, collimator, reflective sight.
