  Obviously you now nothing about that market. The SOCOM should shortly order a btach of a few thousand weapons for eval, then they will start ordering bigger quantities if they are satisfied (and they look so). So the SCAR is just a matter of time, but probably next year some units will already be aquipped with it. And NO, they are absolutely not compatible with the M16 so the parts and the guns will probably be sold to some other countries still using that old design.
