The Picatinny rail has a similar profile to the Weaver, but the recoil groove width of the Picatinny rail is 0.206 in (5.23 mm) versus 0.180 in (4.57 mm) of the Weaver rail/mount, and by contrast with the Weaver, the spacing of the Picatinny recoil groove centers is consistent, at 0.394 in (10.01 mm).

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).
The only significant difference between the MIL-STD-1913 rail and the similar Weaver rail mount are the size and shapes of the slots. Whereas the earlier Weaver rail is modified from a low, wide dovetail rail and has rounded slots, the 1913 rail has a more pronounced angular section and square-bottomed slots. This means that an accessory ...
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.
An example could be to mount a scope with a 1-inch (25.4 mm) tube in a 30 mm mount using a plastic insert. There are also special ring mounts in the market with circularly shaped ring inserts made to provide stress free mounting without lapping, with Burris Signature Rings and Sako Optilock Rings as two well-known examples.
AN/PVS-4 (Night Vision Sight, Individual Served Weapon, AN/PVS-4) is the U.S. military designation for a specification of the first second generation passive Night vision device. The AN/PVS-4 first saw widespread use during the Gulf War and later some deployment in the Iraq War and has since been replaced by modern third-generation weapon sights.
The telescopic sight proprietary mount is adjustable for tension on the SVD rifle's side rail scope mount. This side rail is a type of dovetail rail known as the Warsaw Pact rail, which has cut-out portions to reduce weight and allow easier installation. The side rail mount is an offset mounting that positions the PSO-1 telescopic sight axis to ...
Imaging of dim celestial targets, usually deep sky objects, requires exposure times of many minutes, particularly when narrowband images are being taken. In order for the resulting image to maintain usable clarity and sharpness during these exposures, the target must be held at the same position within the telescope's field of view during the whole exposure; any apparent motion would cause ...
