Spiral fluting

[InF1uxx]

As far as i am aware the spiral fluting makes the barrel lighter due to the removed material and also reduces heat due to the increased surface area, increasing accuracy, this can actually increase the heat of the rifle due to removed material though. Unless you are running under sustained automatic fire i don't think the heat of the barrel will matter all that much and you will most likely worry more about recoil and muzzle rise than the opening of the group. It has its purpose but for the average consumer i wouldn't suggest it other than for looks, I would stick with a thicker barrel profile.
