A red dot sight is a common classification [1] for a non-magnifying reflector (or reflex) sight that provides an illuminated red dot to the user as a point of aim. A standard design uses a red light-emitting diode (LED) at the focus of collimating optics , which generates a dot-style illuminated reticle that stays in alignment with the firearm ...
A view through a Tasco ProPoint red dot sight. The mid- to late 1970s saw the introduction of what are usually referred to as red dot sights, a type that gives the user a simple bright red dot as an aiming point. [27] The typical configuration for this sight is a compact curved mirror reflector design with a red light-emitting diode (LED) at ...
Usually this results in the telescopic sight being offset to one side (to the left for right-handed people, right for left-handed) to allow the shell to clear the telescopic sight. Alternately a scout rifle -type mount can be used, which places a long-eye-relief telescopic sight forward of the action.
The mount is found on the left side of the rifle receiver, with machined cutouts for reduced weight and ease of installation; an example is the PSO-1 optical sight. Similar rails can also be found on rifles such as the Dragunov sniper rifle (SVD), the PSL rifle , the PKM as well as some AK series assault rifles from 1954 onwards.
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 normally done at a range of 200 m. Windage adjustments are made on the left hand side of the base, using a flat object such as a flat-head screwdriver or a coin. The windage adjustment is ...
The sight is designed for use with the M16/M4 family of rifles, but can be mounted on any weapon fitted with an upper Picatinny rail. It is also NVG-compatible—the aiming dot is still visible through night vision scopes and goggles. The Army's M68 designation was also applied to a later version of the sight, the Aimpoint CompM4.
