The MILITARY ARMAMENT CORPORATION MODEL 11, officially abbreviated as " M11"
or " M-11", and commonly known as the MAC-11, is a machine pistol/submachine
gun developed by American firearm designer Gordon Ingram at the Military
Armament Corporation (MAC) during the 1970s in Powder Springs, Georgia, United
States.[4][5][6] The weapon is a sub-compact version of the Model 10 (MAC-10),
and is chambered to fire the smaller .380 ACP round.<ref name="Assault"/>
This weapon is sometimes confused with the Sylvia & Wayne Daniels M-11/9, its
successor the Leinad PM-11, or the Vulcan M-11-9, both of which are later
variants of the MAC chambered for the 9 mm Parabellum cartridge.[7]<ref
name="Walker"/> Cobray also made a .380 ACP variant called the M12.[8]
** Design
*** Operation
Like the larger M-10, the M-11 has iron sights with the rear pinhole sight
welded to the receiver. These sights are for use with the folding stock, as
using them without the stock is nearly useless because of the initial jump of
the weapon due to its heavy, open-bolt design. The M-11A1 also has two safety
features which are also found on the Model 10A1. The charging handle rotates
to 90 degrees to lock the bolt in the forward position thus preventing the
weapon from being cocked. The second safety is a slider that is pushed
forward to lock the trigger, which in turn pins the bolt to the rear (cocked)
position. This prevents the weapon from discharging even when dropped, which
is not uncommon with an open-bolt design.
*** Performance
The rate of fire of the M-11A1 is one of the biggest complaints about the
firearm. Listed as 1,200 rounds per minute,<ref name="Walker"/> the MAC-11's
high cyclic rate is able to empty the entire 32-round magazine in about two
seconds, which many users view as a drawback.[9] Extreme trigger discipline is
required to discharge short bursts, which are required for combat
effectiveness. Without proper training, the natural tendency of the
inexperienced shooter is to hold down the trigger, discharging the entire
magazine, often with poor accuracy due to recoil. The rate of fire also
varies depending on the weight of bullets used.[date=April 2023] The gun also
has a selector switch that allows it to fire only one round at a time in
semi-automatic mode.
Noting the weapon's poor accuracy, in the 1970s International Association of
Police Chiefs weapons researcher David Steele described the MAC series as "fit
only for combat in a phone booth".[10]
The M-11 is the least common version in the MAC family of firearms.[date=April
2023]
*** Sound suppressor
A specific suppressor was developed for the MAC-11, which used wipes as
baffles, instead of the reflex baffles that Mitchell WerBell III created for
the MAC-10. Though wipes are less durable than reflex baffles, they had the
advantage of proving quieter for the MAC-11. The suppressor is [224] long and
is covered with Nomex, a heat-resistant material.<ref name="Hogg"/>
** Manufacturers
