Shhh, he's still writing his supah dupah long post about his hax :D
Edit: The article posted by kingCHUBBY is a very interesting article - lots of good stuff in there. I also agree with yopa, noscoping a spawning target is effective because they can be taken down by your buddies using the AR (usually newbies using it semiautomatically - with at least 0.5s delay, I may add) - I find I'm noscoping most of the time when the opponent is too close for comfort - i.e. 5-6 metres away, and scope when I am ambush headshotting, have a decent chance of headshotting or the opponent is far away.
