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 ...
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 ...
Sight magnifiers are optical telescopes that provide increased magnification to a shooter's view when they are engaged. They are commonly mounted behind red dot and holographic sights that produce a collimated reticle image. Most have mounts which allow them to flip to the side when not in use, though immobile mounts exist as well. [2]
The optical window in a holographic weapon sight looks like a piece of clear glass with an illuminated reticle in the middle. The aiming reticle can be an infinitely small dot whose perceived size is given by the acuity of the eye. For someone with 20/20 vision, it is about 1 minute of arc (0.3 mrad). [citation needed]

The first ACOG model, known as the TA01, was released in 1987. [3] [4] An example was tested on the Stoner 93 in the early 1990s by the Royal Thai Armed Forces. [5]In 1995, United States Special Operations Command selected the 4×32 TA01 as the official scope for the M4 carbine and purchased 12,000 units from Trijicon. [6]
