From the AR-15 primer on this site:

'-floating the barrel does exactly that. It "floats" the handguards off the barrel, making your rifle like a hunting rifle where no "pressure" from the handguard can be transferred to your barrel. Most people report that "free-floating the barrel" decreases their groups at 100 yards from something like 1.25" to .75". '

I recommend that you read the primer.  It has a lot of great information:

Free floating allows the barrel to be suspended without anything coming into contact with it, such as handguards or slings. This allows the the barrel to vibrate freely and consistently, an important part of acheiving accuracy
