AK47s are inferior weapons at range; the short, fat 7.62x39mm round has terrible ballistics past a couple hundred meters, and it loses velocity a lot faster than the SCAR's 7.62x51mm. If you're going to upgrade to a larger caliber, you might as well go to one that doesn't suck ass compared to the rest of the 7.62 family.
