CornerShot CornerShot is a weapon accessory invented by Lt . Col . Amos Golan of the Israeli Defense Forces in cooperation with American investors . It was designed in the early 2000s for SWAT teams and special forces in hostile situations usually involving terrorists and hostages . Its purpose is similar to that of the periscope rifle ; it allows its operator to both see and attack an armed target , without exposing the operator to counterattack . Overview . The concept was first developed in Nazi Germany during World War II in the form of the StG - 44 ' s Krummlauf , a curved barrel with a mounted mirror developed for urban warfare ; however , a similar concept , the Periscope rifle , was developed by Australian troops in the trenches of the Western Front in World War I . This earlier idea was simply a specialised " second " stock and trigger mechanism combined with a periscope to allow the shooter to remain safely " within " the trench and still aim and fire a rifle that was laid over the top of the trench . The CornerShot variations developed so far are the Standard , the 40 mm grenade launcher , the APR , and a derived anti - tank version . It works , because its many parts are either on the muzzle or the butt end , which are connected by a steel hinge . It is manufactured by Corner Shot Holdings , LLC , a company based in Miami with an office in Israel . There is another separate manufacturer for the CornerShot in France called OMEGA - Cornershot . Units have been sold in 15 countries . The CornerShot was recently evaluated by the UK Ministry of Defence . Forms and variations . The CornerShot ' s shooting range is claimed to be accurate and effective to 100 meters in 9x19mm , . 40 S & W , and . 45 ACP pistols , and is claimed to be effective to 200 meters with a 5 . 7x28mm pistol . 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 and tactical flashlights , suppressors and rubber bullets A standard pistol version is available , along with a 40 mm grenade launcher . Because they are fitted with high - resolution digital cameras , any variant can also be used as a surveillance tool . All the models come with the same stock camera and 2 . 5 in . color LCD monitor , providing a video observation and sighting system with transmission capability . The flashlight and camera lets it operate in either day or night . A variety of optional interchangeable cameras , as well as a folding stock , are available , and a universal accessory rail is standard . Future versions will be mountable on the US M - 16 and a European joint assault weapon . 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 2 - hour ' flash memory ' chip attached to the gunstock . Standard . The standard CornerShot mounts a normal semi - automatic pistol in the front part of the weapon , with a remote linkage to the trigger mechanism in the rear part , it has a trigger pull of 21 newton s ( 4 . 7 lbf ) . It is 820 millimetres ( 32 . 67 in ) long , with a weight of 3 . 86 kilograms ( 8 . 5 lb ) . 40 mm grenade launcher . The 40 mm Grenade Launcher is a breech - loading , single shot grenade launcher .

It can turn 90 degrees instead of the standard 60 degrees The Panzerfaust - has a little info about the CornerShot Panzerfaust ( and tells the name of the CornerShot Panzerfaust ) How it works . In the standard version a pistol is mounted in the front end of the weapon , which bends horizontally at a mid - gun sixty - degree hinge There is a digital camera and a flashlight attached to the barrel in the bayonet position .

South Korea . South Korea had publicly unveiled their own version of the CornerShot on March 23 , 2010 , created and developed by the Agency for Defense Development . The ADD had ₩350 million invested for research and development of their own CornerShot in September 2008 .
