Among scopes for rail mounts, the 22.5-degree V-shaped Zeiss rail is the most prevalent standard. It was introduced in 1990. After the patent expired in 2008, compatible scopes have been offered from manufacturers such as Blaser, [1] Leica, Minox, Meopta, Nikon, [2] Noblex (formerly Docter [3]), Schmidt & Bender [4] and Steiner.

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 mount is compact enough to be used on pistols, as well as rifles and shotguns. The dovetail is approximately 16.5 mm wide, and is radiused so as not to have any sharp edges. Also used on Aimpoint Acro C-2 and P-2, as well as Steiner MPS, Viridian RFX 45, CH Duty, Lucid Optics E7 [ 18 ] and Vector Frenzy Plus.

It is similar in concept to the earlier commercial Weaver rail mount used to mount telescopic sights, but is taller and has wider slots at regular intervals along the entire length. The MIL-STD-1913 locking slot width is 0.206 in (5.23 mm). The spacing of slot centres is 0.394 in (10.01 mm) and the slot depth is 0.118 in (3.00 mm). [8]
The optics are considered exceptional, even by contemporary standards and the biggest drawback compared to modern scopes is the weight. Although the AN/PVS-4 has not had a great deal of cultural impact, its legacy of high quality night vision has become a staple of movies and television shows which often do not show real equipment.
The locking bar system allows for even stress to be distributed and prevent canting of the scope mount. Another form of scope canting is caused by the rings themselves. Many Weaver-type mounts, including many Picatinny-type scope rings and even the Redfield Type, have either two or four screws on top of the scope ring that hold the scope in place.
Weaver rail mount, early rail system used for scope mounts, still has some popularity in the civilian market; Picatinny rail (MIL-STD-1913 or STANAG 2324 rail (cancelled)), the improved and military standardized version of the Weaver mount developed by Picatinny Arsenal in New Jersey. Used for both for scope mounts and for accessories (such as ...
