Im not usre that someone else has answered this allready, but here goes. It is to do with the barrel harmonics. Every time a shot is fired the barrel vibrates, the less touching it the better since it will allways vibrate the same way giving your bullets a more predictable path, thats why a free floating (barrel only comes into contact with anything at the breach) barrel is preferable for sharpshooting. With gas operated semi automatic rifles this is not possible since there is need for a gas take off point to cycle the action and in some rifles the actiopn begins to cycle before the first roun has left the barrel causing more vibration possibly altering the course of the round.
