You couldn't be more wrong about LevelCap. He's very good, not the best but very good.
I've watched all of his videos since subbing his channel and he never gave a hint that he's "cheating". I've seen him outshooting people, I've also seen him being gunned down many times. He's what you call a "pubstar", and his video usually is of him preying on the normal players.
Anyways, it's possible to control the recoil of the M416 while firing at full auto by pulling down slightly on the mouse. Just go on an unranked server and practice shooting against a wall. I'm too lazy to "practice" so I just prefer to burst fire *shrug*

Those are medium range at most, I would qualify them as short range especially on the meat grinder that is Noshahr TDM. The M16A3 will completely destroy the M416 at real ranges, especially in semi-auto (a fire mode this guy likely has no clue about).

Many of these videos are now made by TDM junkies. Almost everyone he shoots is running so head height is easy, very few are crouched or prone and none are moving with teammates. So it becomes, drop health at your feet, get partial hard cover, reload after every kill...rinse and repeat. Not very useful for TG server type play, but if you want to get good at it there are plenty of servers where you can find just this sort of twitch gaming.
