The Ingram submachine gun has been designed by an American arms designer Gordon B. Ingram. He began work on this compact SMG in the mid 1960s. Several prototypes were made by 1965. It was mainly intended for special operations and law enforcement forces. This submachine gun was purchased by the US Army for trials and evaluation, however it was not accepted to service. Production of this weapon commenced in 1970 by the Military Armament Corporation (MAC). In 1976 the MAC went bust and production rights of the Ingram SMG were transferred to RPB Industries Inc. Later it was also manufactured by some other companies.
Ingrams were exported to Chile, Yugoslavia and some other Asian and South American countries. Copies of this SMG were manufactured in Japan, South Africa and Taiwan.
This submachine guns has been designed for close encounters and concealed carrying. It is a blowback- operated, selective fire weapon, that fires from open bolt. There are two baseline MAC-10 (or M10) models, chambered for 11.43 (.45 ACP) and 9 x 19 mm rounds.
This weapon is simple in design and technology.
