My notion is not based on that assumption. But FN SCAR really cost so much and Pakistan have always look for cost effective solution. If SCAR is purchased it will be very surprising but it have less chances than BREN.
Do you know the definition of letter of understanding ?
Did FN announce that they are negotiating like CZ did ?
Do you think FN will continue to support during war as they are highly influenced by US ?
So SCAR have more chances even without signing any LOU. and we haven't heard anything from them. SCAR is a weapon that Pakistan will purchase in small numbers for SSG and not for service rifles. And SCAR cost so much that European countries have difficulties in purchasing it .
SCAR = expensive...
