Basically. Only thing that really makes a difference is the texture, how well you bake down the high poly, and the kind of attachments you use. But this and the AK are probably the two most over modeled guns. I simply undertook the task because I happen to own an AR-15 and it made it super easy to model having it in my lap. It was probably about 24 hours total of modeling time on the high poly, if that. Plus being one of my more favorable rifles it was fun to make.
