Overview
The Ingram MAC-11 is a compact, blowback-operated, open-bolt submachine gun designed by Gordon B. Ingram and produced by the Military Armament Corporation in the early 1970s. A scaled-down version of the larger MAC-10, it is chambered in .380 ACP and feeds from detachable 16- or 32-round box magazines. With an extremely high cyclic rate of around 1,200 rounds per minute and a telescoping wire stock, it was intended for close-quarters use and concealed carry, and its threaded muzzle readily accepts a suppressor.

Notes
The MAC-11 is smaller and lighter than the .45 ACP and 9mm MAC-10, trading power for compactness. Its very high rate of fire makes it difficult to control, so a wrist strap or suppressor was commonly used to steady the weapon. Later production was continued by RPB Industries and various successor firms after MAC closed in 1976.
Background
Gordon Ingram's compact machine pistols became icons of 1980s action cinema and, fitted with the two-stage SIONICS suppressor, were closely associated with covert operations and clandestine units.
