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.

[citation needed] Compatible scopes have an internal dovetail rail where two or more 45-degree wedge nuts can be slid in. For example, EAW uses wedge nuts with M5 or M4 threads. [11] The scope mount is then attached using simple hand tools like a torx key or hex key to a torque between 4–5 N⋅m (3.0–3.7 lbf⋅ft). [12]
The sequence of lens designations may differ in literature. See also full list of Nikon designations, Sigma designations, Tamron designations and Tokina designations.. Nikon AF-S/Sigma HSM/Tamron USD or PZD: The lens contains an integrated ultrasonic focus motor based on piezoelectricity, which enables quiet or low noise autofocus operation.
The G-41(m) and G-41(w) semi-automatic rifles had ZF40 scopes added in small quantities for test and evaluation in the field. MP-43, MP-44 , FG-42 automatic select fire weapons had the ZF41/1 fitted for test only, these were not produced past prototype stage, the ZF4 scope was then used on these weapons instead.
Nikon produced a large range of Nikkor-branded lenses for these cameras with focal lengths ranging from 21 mm to 1000 mm.Several other manufacturers including Fuji (now Fujifilm), Komura and Zunow made S-mount lenses at the time of which the Zunow 5 cm f /1.1 lens is a keenly sought after collectors item.
The SIG Sauer 200 STR has an 11 mm dovetail on the receiver for mounting a diopter rear sight or a scope sight, either directly or via a Picatinny rail adapter.. Dovetails come in several different types and sizes depending on manufacturer, but the most common are the 11 mm and 3 ⁄ 8 inch (9.5 mm).
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]
