Type 730C is a new variant unveiled in February 2017 that combines the existing Type 730 seven-barrelled 30 mm rotary cannon with 6x FL-3000N missiles. The system comes with LR66 tracking radar and OC8 electro-optical tracker, though not fitted on the CIWS probably due to weight and electromagnetic interference issues, to track two separate ...
The 30mm DS30M Mark 2 is a ship-protection system made by MSI-Defence Systems consisting of a 30mm Mark 44 Bushmaster II cannon on an automated mount. It was designed to defend Royal Navy frigates from fast inshore attack craft armed with short-range missiles, rocket-propelled grenades , machine guns , or explosives.
The complete weapon system is called A-213-Vympel-A, which comprises the AK-630M Gun Mount, MR-123-02 Fire-Control Radar System, and SP-521 Electrical-Optical Tracker. A single MR-123 radar system can simultaneously control two guns, either two 30 mm gun mounts, or two 57 mm gun mounts, or one 30 mm gun and one 57 mm gun.
It is a static Very Short-Range Air Defense (VSHORAD) Counter Unmanned Aerial Systems (C-UAS) system that can be deployed off a truck. The system combines radars, EO/IR cameras, and laser rangefinders with a 30 mm Mk44 Bushmaster II chain gun with 240 rounds of airburst munitions capable of engaging small UAS out to 2 km (1.2 mi).

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.
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 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.
