MAC-10

   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 designed 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 is 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. It's receiver is made from sheet steel and consists of two parts. These are held together by a steel pin. Generally it is a reliable weapon.

   Cocking handle is located at the top of the gun. It stays stable when the gun is fired. It comfortable to reload the weapon using either hand. This cocking handle also adds safety as it locks the bolt in forward position, when turned 90 degrees sideways. There is on clear sight vision, when the safety is turned on. Another safety switch is located inside the triggerguard. A separate fire mode selector is located above the triggerguard on the left side of the weapon. It has single shots and full-auto modes.

   The Ingram SMG is fed from a box-shaped magazine, inserted in the pistol handle. The .45 ACP model comes with 30 round magazines, while the 9 x 19 mm is fed from 32 round magazines. This weapon can be fired by holding with one hand. A leather loop is attached to the front of the weapon, to provide additional stability. It is held by a non-firing hand.

   Effective range of fire is limited to 50 - 70 meters. It's firing accuracy suffers as this weapon is uncomfortable to hold with both hands and it becomes hard to compensate recoil power.

   The Ingram M10 has non-adjustable diopter-type sights of the most simple type. This SMG comes with a telescopic steel wire stock. Some of it's versions were fitted with detachable wooden buttstocks. This submachine gun is compatible with silencers. Silencers on this weapon are quite efficient, as it uses subsonic bullets.
