The Israeli Corner Shot gun is an oddity derived from the Third Reich use of a bent-barrel gun (via Krummlauf attachment), only the Israelis made a weapon that is part rifle stock with a pistol grip that operates a flex unit up front that can take standard 9mm-.40 cal pistols as inserts as well as interchangable lights and lasers. A flex sight enables the concealed operator to see around corners and fire. Very useful for CQB (Close Quarters Battle) in hostile areas. The weapon weighs 8.5 lbs and can take a wide range of pistols from around the world. It also can take special grenade launchers. It arcs 60o left or right of center. The Germans knowing the history of that concept one-upped the Israelis and created for them a mini-Panzerfaust weapon for it! In exchange, the Israelis gave the Germans not only the Corner Shot for Special Forces but also many Tavor 21 bullpup rifles as well. The gun can be seen in the movie "Wanted" operated by Angelina Jolie :)
