I must have missed that part when going through all of my MOUT training prior to my deployments where we did A LOT of raids using our M4s. 
In reality, just like anyother gun, it all boils down to what you are trained to use. I am sure there are a fair amount of guys/gals on this forum who like myself, are pretty fast and accurate with our "long guns".
