7.62 is a heavier round so that is a given, question is would you rather have farther range to dispatch people still using 7.62 rifles? Or more power with a lack of range compared. I am no expert but I am just assuming the range of an ak is slightly similar to a weapon using the same calibre for the same purpose (assault rifle).

what does all this mean? AK and FN are nothing alike. other then they are both rifles.
the FN is a Good rifle, the C-7/M-16 is a good rifle, and the AK is a good rifle. but all for different reasons...
nowadays, IMHO the FN is just too damned big to be effective in A-Stan or Iraq... but thats simply my opinion...
cheers
