The MAC-10 is an American-made .45 ACP submachine gun designed and manufactured by Military Armament Corporation. An otherwise unremarkable submachine gun, it's greatest feature is the proprietary Sionics suppressor. A hefty two-stage wipeless suppressor, it is so effective that you can hear the bolt cycling. While export restrictions doomed the company, production was picked up by other firms and loosening restrictions allowed greater export of the weapon. The weapon would later be adopted by various Special Forces units, including US Navy SEALS. A compact weapon that serves .45 ACP at a rate of 1100 rounds per minute, it was the perfect CQB weapon. However, such features made it attractive to the criminal underworld, and like the Thompson before it, took upon a sinister reputation that no doubt led to its ban in the 1994 Assault Weapons Ban, which expired in 2004. Today, the weapon remains reasonably popular with both civilian firearm enthusiasts, commandos, and criminals.
