CornerShot is a weapon accessory created by Lt. Col. Amos Golan of the Israeli Defense Forces in cooperation with American investors.

[1] It was designed in the early 2000s for use by SWAT teams and special forces in hostile situations usually involving terrorists and hostages.

The device is available in several variations, including the Beretta 92F, a model widely used by US security forces, the Glock, SIG Sauer, and CZ.

The mechanism can also mount various accessories such as detachable cameras, audio/video transmission kits, visible and IR lasers, tactical flashlights, suppressors, and can fire rubber bullets.

All the models come with the same stock camera and 2.5-inch color LCD monitor, providing a video observation and sighting system with powerful transmission capability.

The system can also be remotely emplaced and operated from behind camouflage, with a wire video-out connection sending images to a commander at a distance or saved to a two-hour flash memory chip attached to the gunstock.

[3] In the standard version a pistol is mounted in the front end of the weapon, which bends horizontally at a mid-frame sixty-degree hinge.

The periscope rifle was independently developed by a number of individuals as a response to the trench warfare of World War I; they were used by armies of several countries from 1914 onward.

[6] Both models were first unveiled at the 4th China Police Expo (CIPATE) and developed by the Chongqing Changfeng Machinery Co Ltd and Shanghai Sea Shield Technologies Company.

[20] The CSWS's camera, laser, infrared illuminator, and torch are positioned in the front while the display, electronics, battery, and swivelling mechanism are located in the back.
