i don't think so, i'm sure.
There's Rmax range on paper, and effective Rmax range (when the missile still has some energy to manoeuver and actually be a threat)
while you may obtain an IR signature at 11Nm, hitting a moving target at this distance with a fox 2 in DCS is a different story.
Anyway, again if there is an issue with the M2KC, i hope Razbam fixes it, so F18 drivers can stop raising the bug flag everytime they get their a$$ walloped in short range by a better dogfighter lmao !
