Design
edit
Operation
editLike the larger M-10, the M-11 has iron sights with the rear pinholesightwelded to thereceiver.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-boltdesign. 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
editThe 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 highcyclic rateis able to empty the entire 32-round magazine in about two seconds, which many users view as a drawback.[9]Extremetrigger disciplineis 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]
Sound suppressor
edit
A specificsuppressorwas developed for the MAC-11, which used wipes asbaffles,instead of the reflex baffles thatMitchell WerBell IIIcreated 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 withNomex,a heat-resistant material.[1]
Manufacturers
editMAC-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.
