MAC-10 (Full name: Military Armament Corporation Model 10, aka M-10) is an open bolt  submachine gun or machine pistol developed in 1964 in US. It was built predominantly from steel stampings and has a telescoping bolt, which wraps around the barrel, makes this weapon finish in a compact size and balances the weight over the pistol grip when the magazine is located. However, the open bolt system it used result in a rapid rate of fire and the hard to control the muzzle climp.

MAC-10 shared the same magazine with M3 Grease Gun in order to save the cost of develop a new magazine, also its barrel is threaded to accept a suppressor, which worked by reducing the discharge's sound, without attempting to reduce the velocity of the bullet.
