C79 Reticle as shown in the declassified danish manual of arms HRN 111-00 for the M95 family of rifles (C7,C8 and C8IUR) The reticle of the C79 sight was designed to serve on the C9 Light Machine Gun, thus an appropriate pattern was chosen to aid the gunner in judging distance.
The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.
The FN FAL from which the L1A1 Self-Loading Rifle was derived was not designed for mounting optical sights like the SUIT. To mount the SUIT, a new top cover was designed. This had a rail welded to the top to accept the sight mount, and two tabs at the rear of the pressed sheet steel cover which butted against the back of the upper receiver, preventing the cover from sliding on its rails and ...
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]
[3] [4] In 1962, Leupold invented the Duplex Reticle, which most riflescopes now use. [6] By 1979, Leupold scopes were generating twice the total revenue of Stevens instruments. [3] [7] In 1969, the company acquired a majority interest in the company Nosler Bullets (also a family company), and then sold off their portion in 1988.
The M145 Machine Gun Optic is a variant of the C79, which is different to the standard version in that ballistic compensation is in the reticle rather than in the mount. Reticle illumination is by a battery-powered LED with eleven brightness settings. It is used by the US military for its M249s and M240s.
The reticle of the SUSAT is of unusual design. Unlike the traditional crosshair layouts commonly used, which are in essence a cross intersecting the target, the SUSAT has a single obelisk-shaped post protruding from the bottom edge of the sight. This type of reticle is sometimes referred to as the "German Post".
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 .
