The Mac 11, also known as the Military Armament Corporation Model 11, is a highly compact submachine gun designed and manufactured by the Ingram MAC-11 company. As one of the smallest fully automatic firearms in the world, the Mac 11 is frequently used by military and law enforcement personnel when a small, concealable weapon is required. The Mac 11’s lightweight construction, high rate of fire, and simple operating mechanism make it ideal for close-quarters combat scenarios, although its accuracy is often limited by its short barrel length. Despite some controversy surrounding its capacity and potential for illicit use, the Mac 11 remains a popular choice amongst those in need of a highly concealable and versatile weapon.
