The original Military Armament Corporation was formed in 1970 in Powder Springs, Georgia, by quantum corporation investors, Gordon Ingram (designer of the MAC-10), and Mitchell WerBell III (owner of SIONICS). That company famously produced the MAC-10 and MAC-11 machine pistols before running into political and financial trouble, stopping production in 1973 and filing for bankruptcy in 1975. Introduced around 2023, the MAC-2 line (including variants like the MAC-2 Tactical Wood and MAC-2 3-Gun) was built using an inertia-driven operating system similar to classic combat/defense inertia shotguns (often dubbed a "Turkenelli" by enthusiasts due to its functional similarities to Italian design layouts). This gun is missing the end cap; that is why it's stated 1 shot as seen in photos.
