Walter you have to fix these things, simple things like CI images not included or named incorrectly in the .cs file need to be addressed as soon as they are mentioned. This doesn't mean you have to devote every sweat and tear to modding, just be more motivated to fixing these things.
Also referring to the people who mentioned your weapons have elongated (The hands are far out) hands. You have the mountPoint node in an odd position. Place it exactly where the right hand is in the model. Especially when I edited your HK416, the mountPoint node was higher up in the model; wrong.
