Or China. China makes an M-16 Clone, for export only. They don't use it. At first they were only "near clones", with different grip, buttstock, and front sight.
Now they are much closer, at least in appearance.
Iran also produced a direct copy of the earlier Chinese near clone above. -
Iran still produces the Chinese M-4 lookalike. If I remember correctly, a Iranian commando team was found with these in Iraq.
