The model is just...meh
What we need is something called the MachineGun. It should look something like the gun.
Edit: 2 Guns, one duped in front of the other and some edits like taking out the bullet ejecter on the one in front, and the trigger on the one i front, along with the beggining "scope notch" on the second one and the ending notch on the first to be deleted, so it looks like one larger gun.
