I don't know why you guys have problems with the g43...
I frankly could only very rarely get my hands on it, but when you follow two simple rules you won't have any problems with it.
1. use it like a bolt rifle. aim like a bolt rifle, press the trigger a bit earlier.
2. position, position, position. Mid range, urban setting.
but that could be applied to all semi auto rifles, couldn't it?
I can remember my endless sniping streaks with the G43 on ramelle in the tower.. in the fog distance, beyond the river. they didn't know what hit them, and the SmG guy who tried to kill me up there didn't either.
