Scope mounts are rigid implements used to attach (typically) a telescopic sight or other types of optical sights onto a firearm. The mount can be made integral to the scope body (such as the Zeiss rail ) or, more commonly, an external fitting that clamp onto the scope tube via screw -tightened rings (similar to pipe shoes ).
The user guide engraved into a model of the Antikythera Mechanism. User guides have been found with ancient devices. One example is the Antikythera Mechanism, [1] a 2,000 year old Greek analogue computer that was found off the coast of the Greek island Antikythera in the year 1900.
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 first operating arthroscope was designed by them, and they worked together to produce the first high-quality color intraarticular photography. [35] The field benefited significantly from technological advances, particularly advances in flexible fiber optics during the 1970s and 1980s.
arthroscope; laparoscope; etc. According to rigidity of the endoscope: rigid endoscope: A rigid endoscope is a prismatic optical system with advantages of clear imaging, multiple working channels and multiple viewpoints. flexible endoscope: A flexible endoscope is an optical-fiber-based system. Notable features of a flexible endoscope include ...
While the well standardized Picatinny rail mount (and its less standardized predecessor the Weaver rail) is most known in the U.S., many European gun manufacturers offer proprietary scope base receiver mounting systems for their guns, for example Sako has tapered dovetails, Tikka use a 17 mm dovetail, [5] and there are other solutions such as ...
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.
The current issue model features an improved mounting system for better return to zero. The C79A2 has a green rubber armored cover to help the optic blend in with the Canadian CADPAT uniform. The A2 series is the optics mid life upgrade for the C7A2 program as the tritium needs to be replaced every 8 to 12 years of service."C79A2" is engraved ...
