Leupold & Stevens, Inc. is an American manufacturer of telescopic sights, red dot sights, binoculars, rangefinders, spotting scopes, and eyewear located in Beaverton, Oregon, United States. The company, started in 1907, is on its fifth generation of family ownership.
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 ...
A Leupold telescopic sight mounted on a dovetailed rifle receiver via two scope rings From left: A sketch of a cross section on a Zeiss rail and ring mount, both with a Picatinny rail interface. Scope mounts are rigid implements used to attach (typically) a telescopic sight or other types of optical sights onto a firearm .
The German Army G36 assault rifles have a more or less built in dual combat sighting system consisting of a ZF 3×4° telescopic sight combined with an unmagnified electronic red dot sight. The dual combat sighting system weighs 30 g (1.1 oz) due to a housing made out of glass fiber reinforced polyamide.
A bore-sighting device is usually used to roughly zero the sight before a first-time shooter takes it to the range. 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.
The Weaver mount was developed by William Ralph Weaver (1905 – 8 November 1975) at his telescopic sight company W.R. Weaver Co., which he founded in 1930. [3] Previous systems included the Leupold/Redfield mounts. [4] Compared to the Leupold mount, the Weaver rail is not as strong and cannot be adjusted for windage. [4]
The laser diode in a holographic sight uses more power and has more complex driving electronics than a standard LED of an equivalent brightness, reducing the amount of time a holographic sight can run on a single set of batteries compared to a red dot sight, [7] around 600 hours for typical holographic sights, compared to sometimes up to tens ...
