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 (NATO Reporting Name: Bass Tilt ) can simultaneously control two guns, either two 30 mm gun mounts, or two 57 mm gun mounts, or one 30 mm gun and one ...
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.
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.
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 M27's mount is interchangeable with the XM8 system. [56] As with the XM8, this system can also be mounted on the OH-58 Kiowa. HGS-55. Using a mount similar to that used on the XM8 and M27 series, the HGS-55 was developed by the McDonnell Douglas Helicopter Company (formerly Hughes Helicopters) to use the EX 34 Mod 0 7.62×51mm chain gun.

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]
A Zeiss rail system typically adds height to the scope body, but also gives the possibility for a slimmer scope mount so that the total scope height can become comparable to a traditional ring mount. The added scope body height due to the rail piece on the scope itself contributes about 5.5 mm (0.22 in) to the total height.
