MAC-10/MAC-11 Machine Pistol
The MAC-10 (Ingram Model 10) and MAC-11 (Ingram
Model 11) have been popularized by Hollywood movies since their inception in
the 1970s. Similar to an earlier blowback design, the Israeli Uzi, the
MAC-10 and the scaled-down, lighter MAC-11 are compact, submachine guns (SMG)
capable of impressive rates of fire and barrel climb.
Whereas the Uzi cycled only 600 rounds of 9x19mm
Parabellum per minute, the MAC-10 boasts a whopping 1145 round-per-minute rate
of fire (in .45 ACP) and a 1090 round-per-minute rate of fire in 9mm. And the
MAC-11 doubled the Uzi rate of fire with 1200 rounds per minute with its
smaller, 9x17 Browning Short (.380 ACP) cartridge.
Unlike the Uzi (at nearly eight pounds, unloaded),
the MAC-10 weighs in at six and a quarter pounds unloaded, and the MAC-11
weighs only three and a half pounds.
The world has American weapons designer Gordon Ingram and Military Armament Corporation of Powder
Springs, Georgia, to thank for creation of the MAC-10 and the MAC-11. Ingram
had already developed the Ingram Model 6, when he became interested in
an SMG that was compact, concealable and capable of silenced operation ideally
suited for special ops and clandestine application. In the mid-1960s, Ingram
teamed with former silencer guru Sionics and began production of the MAC
The MAC-10 is a blowback-operated,selective fire weapon that fires from the open bolt. The cocking handle is
located atop this sawed-off SMG 10.6 inches with the collapsible stock
retracted 21 and a half inches with the stock extended. Both the MAC-10 and
MAC-11 feature a threaded barrel to accept Sionic's whisper-quiet suppressor.
Muzzle velocity for the MAC-10 is about 900 feet per second, and its effective range is an abbreviated 160 to 230
feet with a maximum range of no more than 320 feet.
Given the Ingram's light weight and rate of fire, barrel climb on full auto is significant. A leather strap is
positioned below the barrel for the operator to grasp to help reduce barrel
climb. The MAC-10 has seen some action with U.S. Special Forces in Vietnam and
Brazilian military and paramilitary forces specifically anti-terrorist units.
