A fusion of a sniper rifle and machine gun into one. Sniper barrel on top machine gun barrel on the bottom.

A few other neat little features, the stock is a compression stock. So in other words it compresses when the gun fires to reduce recoil. One of the preview images shows three buttons labeled L,FL, and G. The letters stand for L: Targeting Laser, FL: Flash Light, and G: Grenade Launcher. Everything is more compact around the triggers and uses a system similar to that of a tv remote. Just press the buttons to turn on or off the laser or flash light and fire the grenade launcher.

In case anyone is wondering the SMS doesn"t really stand for anything I kind of just tacked that label on.

The model does have a small animation to it for the switching of the triggers.
