MAC-10

The MAC-10  is a submachine gun that appears in Call of Duty 4: Modern Warfare (Nintendo DS) and Call of Duty: Black Ops.

Call of Duty 4: Modern Warfare (Nintendo DS)
The MAC-10 is one of the three SMGs available in Call of Duty 4: Modern Warfare (Nintendo DS), with the other two being the MP5 and the Mini-Uzi. Along with all other weapons in the game, the MAC-10 has no recoil and idle sway when aiming down the sights. The MAC-10 poses a 40-round magazine, an extremely high rate of fire, but lacks stopping power, taking several shots to take down a single enemy, though it is compensated for by the viciously high rate of fire.

In single player, the MAC-10 is used quite often by enemy forces in the SAS missions, but it is not found in USMC missions until "Missile Away".

Call of Duty: Black Ops
The MAC-10 is a confirmed weapon in the seventh installment of the Call of Duty Series. It was seen in official game art that was included in a preview for Black Ops in the Official Xbox Magazine. In the official game art, the MAC-10 was seen without a stock and had a suppressor equipped.
