For example, I believe that with sub-machine guns you can move faster while aiming down sight. Are there any other differences like this either between weapon types or between weapons within the same type?
Also, do the damage, accuracy, etc. meters between the different weapon types match up? Is 5 bars of damage for an Assault Rifle the same as 5 bars of damage for an LMG?
The reason that I bring this up is that I've been a fairly below average player, but the other night I created a new class with the Galil. Maybe it's my imagination, but it seems like the kick on it is much less than other weapons (including other Assault Rifles). I've been dominating since then. Maybe something just clicked in my play or I've been lucky in server placement, but like I said it seems like the gun is more accurate and I have a much better KDR than even the AK47 or AK74u.
