Fluted ar15 barrel question

[gulfdiver]

What is the difference between a fluted ar15 barrel and a non fluted barrel?
What does it do?

Thanks

Well it helps with the weight.....and its been said that it helps cool the barrel down quicker. They look nice sometimes.

Pretty much spot on. The flutes (grooves) in the barrel increase the surface area of the barrel, allowing it to cool faster. Also, don't they add some rigidity to help with barrel harmonics.
