This is a gun I created for a game I'm working at. It currently has two buttons: one for turning the tactical flashlight on/off and one to turn the two mini-guns on the side on/off. There is also a switch to turn the gun to "auto / three shots / safety" modes. Finally, to give a shark look, I added a shark head in the front with the gun cylinder (I don't know its name) sticking out of its evil mouth and a shark fin where a red dot site is placed in the top. It is about 14k triangles so I thinks its pretty low poly :)
Credits go to me for all parts of the model except the red dot site which goes to @john95. Please give me credits if your planning to use it and please try to tell me how I can improve this model.
BTW, the model was created in blender v.2.56a but I couldn't find this version in the dropdown menu so I picked version 2.6.
