This is my model of a SCAR, I can't remember which SCAR it is. it is low/mid poly I'd say low poly, but I do not know enough about 3D and such to tell. it's blender internal, and doesn't have any good detail materials. it comes with two barrels: silenced and not. It is suppoed to have a red dot sight or something similar, therefore the ironsights are not proper. It isn't rigged, and the lighting is poorly done.
It's simple and without much detail, but should work for some purposes.
