Miranescan M17A1 Submachinegun

This is a Miranescan M17A1 .45 A.M.P. Caliber Submachine Gun, used by the Marine Corps and Army. The weapon fires .45 Automatic Military Pistol Rounds, one of the three calibers of small-arms bullet that the Miranescans use (the others being .30 caliber and .50 caliber). The weapon is popular with the military because of it's high rate of fire, stopping power, and reliability.

Basically, I just put an RIS onto a Thompson Submachine-gun, then painted the whole thing matte black. I wanted a retro-futuristic look for my Coalition of Human Territories, so I'm giving them all World War II style weapons.
I did this using an online program found at this [link]
