Unfortunately these are only the multiplayer weapons. They all appear in the storyline, but not included here are heavy weapons or dlc stuff. Also take note that the workbench pictures are not necessarily what the weapon looks like as some of the pictures have mods on them which can change color, add scopes, longer barrel, ect. What it really looks like can be found above the description. Also note that the stats aren't really comparable as the number following the name indicates how upgraded it is and there is a big difference between a II and X.
