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. [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. [6]

Contents

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] [2] Cobray also made a .380 ACP variant called the M12. [8]

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, [2] 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.[ citation needed ] 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.[ citation needed ]

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 mm (8.8 in) long and is covered with Nomex, a heat-resistant material. [1]

Manufacturers

MAC-type submachine guns and semi-automatic pistols were first manufactured by the Military Armament Corporation, and later by RPB Inc., [11] Cobray (later named Leinad, then Sylvia/Wayne Daniel Inc.), Jersey Arms, MasterPiece Arms, [2] and Vulcan.

<span class="mw-page-title-main">Open bolt</span> System in firearms

A firearm is said to fire from an open bolt or open breech if, when ready to fire, the bolt and working parts are held to the rear of the receiver, with no round in the chamber. When the trigger is actuated, the bolt travels forward, feeds a cartridge from the magazine or belt into the chamber, and fires that cartridge in the same movement. Like any other self-loading design, the action is cycled by the energy released from the propellant, which sends the bolt back to the rear, compressing the mainspring in readiness for firing the next round. In an open-bolt gun firing semi-automatically, the bolt is caught and held at this point by the sear after each shot; and in automatic open-bolt fire, it's caught and held in this manner whenever the trigger is released. In contrast to this, in closed-bolt guns, the trigger and sear do not affect the movement of the bolt directly.

It will also be the secondary armament of the new Puma infantry fighting vehicle. Overall, it is designed to be light, provide maximum safety to the user and function reliably under adverse conditions using a wide range of ammunition from different manufacturers, without the need to adjust the gas system. It was known as the MG43 prior to its adoption by the Bundeswehr.

In 1962 the Italian Army bought a limited number of Franchi LF-57 submachine guns, judged better than the M12 but never issued to the troops, and only in 1992 the M12S2 variant was introduced, in very limited numbers. The Italian Air Force bought instead many M12S and M12S2 for the airport security units. However, the weapon had a higher initial success in the Arab countries and South America.
