Overview
The Ingram MAC-11 (Military Armament Corporation Model 11) is a subcompact open-bolt selective-fire submachine gun designed by Gordon B. Ingram in 1972 and chambered in .380 ACP. A scaled-down derivative of the MAC-10, it was conceived as a compact suppressor-host weapon for clandestine and special operations use. With a cyclic rate approaching 1,200 rounds per minute, it has the dubious distinction of being one of the fastest-firing handheld firearms ever produced, capable of emptying a 32-round magazine in roughly 1.6 seconds. Despite the design's promise, MAC went bankrupt by 1976 and the weapon never achieved widespread military adoption.

Notes
Often confused with the MAC-10 due to similar appearance. The MAC-11's extreme rate of fire and short sight radius made accurate fire beyond a few meters extremely difficult, leading to its mixed combat reputation. After MAC's collapse, derivatives were produced by RPB Industries, SWD, and Cobray, including civilian semi-automatic versions.
Background
The MAC-11 became infamous in 1980s pop culture as a hallmark of crime films and rap iconography, despite being widely panned by professionals - Navy SEAL gun guru Larry Vickers once quipped that the MAC-11 was 'the world's fastest spray-and-pray bullet hose.' Its 1,200-rpm cyclic rate is fast enough that an entire 32-round magazine can be expended in under two seconds.
