10 ingram mac smg max - Ingram Mac 10 SMG machine gum 9mm by Tom Moor

The MAC-10 (Military Armament Corporation Model 10) is a highly compact, Blowback operated, selective fire submachine gun (technically, a machine pistol) developed by Gordon B. Ingram in 1964.
The uniquely shaped suppressor gave the M-10 a very menacing look.

Both the Mac 10 and the Silenced Mac 10 with the unfolded stock are supplied so you can make a simple choice as to which to use without faffing on with changing it.
