For as small as the Uzi is, it has had one of the biggest impacts on the submachine gun world. With more than 10 million produced and used in more than 90 countries, it has been a staple of close combat assault scenarios since 1950. This machine pistol has a 10-inch barrel intended for use in extremely tight spaces like inside tanks or bunkers. Because of the compact size and general efficiency, the weapon was incorporated into most major conflicts and narcotics operations around the world. It uses a blowback open-bolt action that is capable of firing 600 9MM rounds per minute at 1,300 feet per second with an effective range of 200 yards. It can also be chambered in .22 LR, .45 ACP, .41 AE, and 9X21MM.
