looks covered very well here. Fluting imho is for looks. They look really cool! Now I know that some one is going to get mad at me and give a whole speal about some technical mumbo jumbo; I know that some guys talk about weight and rigidity but if you got a big barrel it looks so much cooler if its fluted. If there is an accuracy difference, I cant tell it. I suppose the big boys who are doing serious shooting and trying to win some plastic know what they want for a good reason, but to me its all about the looks.
